RSS Viewer unknown error

Hi all,
we have added a RSS Viewer webpart to one of our Teamsites. This is a Intranet solution.
We receive the following (generic) error message:
"Unable to display this Web Part. If the problem persists, contact your Web server administrator."
To be honest, I do not know where (which log) to check besides the Application Event Log, IIS log.
My Googles lead to quite a few possible causes and solutions, but I seem to be stuck.
Help would be appreciated,
Pim

Hi Taitun,
From your description, my understanding is that you get an error message after you add a RSS Viewer Webpart to your team site.
Please check uls log in path
\Program files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS. You could refer to these articles:
http://samirvaidya.blogspot.jp/2012/03/where-are-sharepoint-uls-logs.html
https://msdn.microsoft.com/en-us/library/ee210652.aspx
I wonder if you will get this issue when you add another type Webpart to your team site.
Besides, could you provide a screenshot about your error message?

Issue with Windows Photo Viewer: "can't save picture because an unknown error occured"

Hi,
I recently installed Windows 7 RC (Build 7100). I quite often have an issue in Windows Photo Viewer when rotating an image and trying to go to the next picture. It gives me the error "Windows Photo Viewer can't save picture because an unknown error occured".
Seperate from this issue: when I delete a picture in Windows Photo Viewer, it is still in the Windows Explorer overview of files. This did not use to be the case in Windows XP?
Kind regards,
Frederik

Hi
SOSv2 ,
This should be fixed in Windows 7 RTM.
Also, you can install Windows Live Photo Gallery to view and rotate pictures as well. To download it, please click
HERE . For more information about Windows Live Photo Gallery, you can
a question on
Windows Live Answers
In addition, please understand that Nikon RAW images (and most Canon) do not support rotate functionality in Windows Photo Viewer, and thus rotate is
disabled. To rotate those types of images, the user will need to use an image editing program that fully supports their RAW codec.
Regards,
Linda
I am using Win 7 x64 Ultimate RTM and still have this problem (with JPG's dumped from my Nikon to the hard drive). Doesn't do it on every one that I rotate, but still very annoying. Is there a fix?

Unknown Error (-4) when trying to submit podcast RSS feed

I have been having this problem for two days now. I'm trying to submit the RSS feed://www.toikids.com/physicians/peds.xml to the store and I get the following error message every time.
We could not complete your iTunes Store request. An unknown error occurred (-4). There was an error in the iTunes Store. Please try again later.
I get his message when using http:// and feed://. I have validated the feed and have tested it in iTunes and in my browser, so I know its not the feed. I haven't found anything about "unknown error -4" either. Any suggestions?
I'm using iTunes 8.1.1 (10) if that matters.

Seems like Apple is at least aware of the issue. I got this response from Apple Support:
+I'm sorry this error message is persisting. Apparently there is an issue with submitting podcasts today and Apple is working hard to correct it.+
+I recommend waiting until tomorrow to try submitting again and replying to this email by Tuesday if the error happens again.+
+I know this is an inconvenience and for that I sincerely apologize. I appreciate your patience with this, Jeff!+
Sincerely,
Kev

Nokia 5800 RSS Reader broken "unknown error"

My Nokia 5800 RSS Reader spontaneously died. Getting "unknown error".
Anyone know how to fix this? Will any new firmware fix it? Any free apps?
The RSS Reader on the phone isn't bad imo and i had over 10 feeds in there. I'm having to use Opera Mini rss feed is usable but that browser is so fragile!
(I have v2.1 fw)
Much discussion about this here but no solution: http://www.allaboutsymbian.com/forum/showthread.php?p=425392
Appreciate my posts? - gimme some kudos and click teh star!

I have had the same problem on my nokia 5800, everything worked great for about 1 month since I bought the phone and then out of nowhere the feeds got corrupted when I was doing a refresh all I think. It is 100% a software database or broken file issue. I tried searching for bookmark database in system folders and files and others using y-browser to see if I can erase them manually but wasn't able to find any file that would indicate it is a bookmark database or whatever. Maybe someone who knows s60 ins and outs has an idea where do these bookmarks live.
On the other hand I remembered I had done a full back up of my phone beforehand using PC suite (Ovi Suite same thing in a different package) . So I just restored the bookmarks to my phone and vioala. The feeds work again, because the whole bookmark database got overwritten. No hard reset required.
If you already have the error and no back up then it is a problem. You would have to trick the nokia restore software to do the restore with a blank file. You will have to dig around and find out how to do it. Perhaps do a back up for the broken bookmarkrs, find the file, then either replace with a blank or edit it such that it looks like blank. Alternatively, have someone who has a uncorrupted bookmark back up, send you the file and you can restore that one.
Hope this helps!Good Luck!

User is running Outlook 2013 home business, and she has a calendar entry that is linked to another mailbox .
When I browse this mailbox from OWA or Outlook client i cannot see this calendar entry.
When the user tried to delete the entry, they receive warning "unknown error" .
It appears the calendar entry is somehow linked to her Outlook profile.
How can i reset this entry without recreating her profile?

Hi
It is a recurring appointment. When you double click on the appointment it states "This is on appointment in a series. What do you want to open?" Click The entire series , and it opens the appointment in READ ONLY mode. When you click Delete
, it throws unknown error.
i have tried the following commands;
Outlook /cleansharing
outlook /cleanreminders
outlook
/cleandmrecords
outlook
/cleanfreebusy
outlook
/cleanprofile
none of which have removed this entry.
I have even tried creating another profile for the user, and this reoccurring appointment is still visible.
The appointment isn't visible on the mailbox where it was created nor is it visible when viewing both mailboxes on OWA.
here is a screen shot showing the issue.

"There was a problem downloading podcast. An unknown error occurred (-50)"

Hello everyone,
When I try to download the latest episode of my podcast feed, I see an exclamation mark next to the episode. When I click on the exclamation mark for more information, I see the following error message:
"There was a problem downloading <podcast_episode>. An unknown error occurred (-50). Please check that the URL is correct and the connection to the network is active and try again."
I was hoping that somebody might take a look at my feed and review the code for any potential problems. It can be found here:
http://www.stereogol.com/audio/wimpy_podcast.php
Important notes:
1. This is not XML code. It is an XML generator created in PHP.
2. This feed used to work fine in iTunes. I had many episodes already downloaded.
3. I began noticing the problem after upgrading to iTunes version 7 and beyond.
4. I know at least 3 other people that experienced the same problem with my feed after upgrading.
5. Upgrading to newer service packs (7.0.2 for example) has not solved the problem.
6. I ran my feed through an RSS validator. It spotted 2 errors: (1) the width of the podcast image and (2) the syntax of the <source> tag. I made corrections but they did not solve the problem. I changed them back after that.
Thanks in advance for any input you can provide.
Pedro

Try fixing up the validation issues...

Not promising it will help, but it's worth a shot.

PLEASE HELP! Keep getting Unknown error (13019) since OS4 load!

Hi,
I've seen the TS2830 and tried EVERY solution including making a new account on my system and still can't sync my iPhone. As a last resort I unselected Sync Music and wiped everything off the iPhone now I can't get it back!!!! AAHHH! I tried only syncing part of my library and still does not work. It looks like it goes thought everything (progress bar counts all the tracks) and then at the ends with the popup "iTunes" "The iPhone "Ray's iPhone" cannot be synced. An unknown error occurred (13019)"
I'm desperate to solve this.
The Windows Event Viewer shows the following errors after each sync attempt:

Project Server 2010 Task page - An unknown error has occurred

Hi All,
I have searched inside the forum for similar problems but i didn't find any solution.
We have Project Server 2010 with December CU installed and
we are
experiencing
a serious
problem with two enterprise resources.
They can login to pwa succesfully but when they enter in the Task page the following error is raised:
An unknown error has occurred
There are no errors reported in the event viewer while in the ULS Log I found only this entry but i don't know if it's related with this issue:

Hi,
I faced exactly the same problem: some resources try to connect to My Tasks, and get an Unknown error. No error message in ULS or Eventlog.
I hope I solved the problem, and want to share the experience here.
First, by reading this article,
http://www.projectserverexperts.com/ProjectServerFAQKnowledgeBase/Unknown%20Error%20My%20Tasks%20Page.aspx: even if the SQL Query returns me no records, it gives me the idea to delete (unpublish) some tasks (i managed to identify some tasks which raised
the problem, by assigning a test account on them, and see that the pb happened).
So I decided to delete my project from the Published Database (and keep it in the Draft of course). Than in Project Pro, I opened and Published: the problem seem to be solved.
I don't know the root cause of the pb: maybe some SQL data were corrupted for an unknown reason.
Hope it could help some one ! Don't hesitate to give feedback if you solved this pb with this solution, or workaround.

Itunes artwork display issue and a fix for 'unknown error occured (-50)'

Too bad they dont have stickies. This would be a great one.
This is a thorough fix for art work and the -50 error.
If you see artwork in itunes, first verify that the artwork is in the mp3 tag using a program like "tag and rename" http://www.softdepia.com/tagrename_download1291.html
If the artwork shows up in tag and rename, then you added it correctly.
If the artwork isn't displaying on ipod, delete the song and retransfer to the ipod. Next make sure the "view artwork" check box is checked. To do this connect your iPod to iTunes and there will be a checkbox that should be checked to see if you want artwork to show up on your iPod.
If you get this message -
The ipod cannot be updated. An unknown error occured (-50).
And have no artwork at all in you IPOD , dont fret. I am getting there..
NO you DO NOT NEED to FORMAT YOUR IPOD YET as commonly posted. I have tested and retested the following fix-
Eject IPOD. Kill ITUNES.
Backup the following files
iTunes Library.itl
iTunes Music Library.xml
& anything in the Previous Itunes library folder
and delete them. More info on these at http://docs.info.apple.com/article.html?artnum=93732
Dont worry, its much easier to recreate the database than to wipe your IPOD.
Next Start up ITUNES. Plug in IPOD. You now should have a empty database.
At this time, uncheck copy ARTWORK to IPOD, and when it's done deleting artwork, CHECK Copy ARTWORK to IPOD.
It now should sucessfully display ARTWORK and not get the -50 error!!
Now, goto you ITUNES Music folder and drag to the library and it will add you music back in, including your PODCASTS.
All you need to do is click the RESUBSCRIBE button and you are back in business!
IF this fails, which i cant DUPLICATE anymore, try this
http://docs.info.apple.com/article.html?artnum=300248
Its the DREADED IPOD FORMAT article.
But you probably wont need it if you follow all these steps.
Post back if this doesnt work and if it does, give me some credit;)

Just as an fyi, to shorten this procedure instead of deleting the files i found out you and open the .itl files and delete all the lines in it so its an empty file.
Then open itunes, and it will rebuild the database with the files from the .xml file.
This saves you from having to rescan the songs..

Whenever I try to open an attachment I get "The download cannot be saved because an unknown error occurred"

Title says it all. If I try to "open" an attachment, the download dialogue comes up and the progress bar begins to fill, then when it should be complete I get the message:
"The download cannot be saved because an unknown error occurred
Please Try Again."
I can still save the files, but then I have to delete them (and that's just a hassle). Any help would be appreciated!

Tools, Options, Attachments, Incoming. Then set to your prefered PDF reader.
An update has reset this to the internal PDF viewer rather than sticking with the one you had before. This reader does not work on my machine.

Why do I keep getting an unknown error when trying to download an app from the app store on my iPod touch 4th generation when I put in the correct password?

I keep getting the same unknown error has occurred when trying to download an app what is wrong?

as an example.. from the sprint forum for a different device (unsure what device.. it's just not an iphone since no iphone or ios device has these settings -- ive seen this advice several times and I believe it's some form of android.. but not sure)
advice from the carrier advisor --
"Clear data in the Dialer and Dialer storage.... under manage Applications> All.
That is Settings - Applications - Choose All to view All choices - then find Dialer and clear the Data. Repeat this for the Dialer Storage as well. I personally also deleted the message thread first from the text message window and my log history which is a menu item from your call screen."
and another for you from a customer -- it is sprint again.. but this time a Samsung Epic
"OMG ... if someone can't tell me how to fix this "9230: Message sent using invalid number of digits..." error, I'm going to scream. My husband and I both have Sprint Epic phones and love them EXCEPT for this one problem! Help!"
Maybe they should sue Samsung?
