Page error when clicking on #hashtag in feed

I've got an issue where if I click on a hashtag in a site feed to see the conversations, I get the below error.  I'm not aware of any special permissions needed?

Below are the lines I believe relating to this problem.  I'm not finding anything specific in the forums about this as yet.

  • Page Not Found Error when clicking on Crystal Report Viewer print icon

    Hi,
        I am working with ASP.NET 2.0 and crystla reportXI release2.
        I am getting "Page Can not be Found " error when clicking on Crystal Report Viewer print icon.
        Could you please tell me how to get rid of this error?
    Regards,
    Smitha

    This sounds like a postback issue. Does your application handle postback by putting the report in session?
    There is a [sample|http://devlibrary.businessobjects.com/BusinessObjectsXIR2SP2/en/en/CrystalReports_dotNET_SDK/crsdk_samples_aspx/data/crsdk_net_tutorials_115_en.zip] to look at on our website. It was created with Crystal Reports XI R2 and Visual Studio .NET but the code will be the same.
    A short pseudocode would be something like this:
    Dim rptDocument As ReportDocument
    If Not Me.IsPostBack or Session("Report") = Nothing Then
    rptDocument = New ReportDocument
    rptDocument.Load(sGlobalPath & "\myreport.rpt";)

  • "The Page Cannot Be Displayed" error when clicking the Remote Agent

    Hi everyone! We have installed ACS SE 4.0 and we have added a remote agent running on Windows Server 2003. Recently, we are encountering "The page cannot be displayed" error when we click the RA under a network device group. This is resolved by rebooting the ACS SE appliance and accessing the ACS SE web console again but after few hours, problem reoccurs. Clicking the links on the ACS SE web console is okay at first but after clicking the RA, every link shows the error "The page cannot be displayed." Hope you could help us on this problem. Anyone's support is very much appreciated.
    Thanks!

    Hi JG,
    Thank you so much for your response. Does Cisco have a documentation that states that this is a known issue with 4.0, such as release notes, for we might need this for the proposal upgrade?
    Again, thanks a lot!

  • Error when clicking send fax in SAP B1 2007A

    Hi,
    I'm trying to configure my client's SAP B1 server to be able to send faxes via SBOMailer and MS Fax. I read the guides and documentation.
    1. Does faxing only work strictly in the scenarios stated in the documentation?
    2. Will it work if:-
    a) The server has MS Fax and a fax modem installed; and
    b) I am logged in to the server via remote desktop; and
    c) I only configured the fax portion of the SBOMailer since I am not using the email function?
    Basically, in this scenario, the Service Manager, SBO Mailer, MS Fax, fax modem and SAP Client (because I am using remote desktop) are on the same machine.
    I am asking this because I keep getting the following error when I click send:-
    "Email address has not been defined for the sender. Cannot send email, SMS, or fax. , 'manager' [Message 3581-4]"
    I have checked the company details, business partner details and the fax console's "sender information". They all have email addresses and fax numbers keyed in.
    After a few minutes, the fax console shows that the system tried to dial to itself and so got a "no dial tone" error. The file that it sent only contained the Cover page and nothing else. What's going on?
    Can anyone out there help me?
    Regards,
    Jin Siang

    Hi,
    Thanks for your advice. That solved one part of the problem. Now the system states "Operation Completed Successfully." BUT nothing appears in the fax console outbox and sent folders. The SBOMailer and MS Fax do not seem to be communicating with each other.
    Email settings are blank because it is not used.
    For fax settings, I put:-
    Microsoft Fax Server: Server IP
    Fax Server Type: Microsoft Fax
    All tickboxes have been checked.
    Schedule settings: On specific date
    Connection settings: Correct login settings
    Database settings: Correct DB selected
    Any ideas, guys?
    Thanks,
    Chris.

  • Error when clicking other button after displaying Popup window

    Hi,
    I'm developing a custom page which calls a popup window in r12, below is the error encountered.
    Error: Cannot Display Page
    You cannot complete this task because you accessed this page using the browser's navigation buttons (the browser Back button, for example).
    To proceed, please select the Home link at the top of the application page to return to the main menu. Then, access this page again using the application's navigation controls (menu, links, and so on) instead of using the browser's navigation controls like Back and Forward.
    On my base page, I have other buttons like Save, Back, and the button to invoke the popup window. I can display the popup window without error, but when i clicked on the base page's other buttons after invoking the popup window, the error above is shown. I'm not clicking any browser's navigation buttons. Please let me know how to solve this error.
    Thanks!

    Hi,
    Just want to update...
    The error occurred because I have isBackNavigationFired checking, this becomes true when clicking the other buttons in the base page after displaying the popup. Is there a workaround where I can make this work without removing my back browser navigation checking?
    Thanks!

  • Pages error when opening .doc file

    I've recently installed Snow Leopard, but I'm still using Pages 2/iWork '06.
    Before I installed SL, I had the same version of Pages installed for my own work as well NeoOffice to open any .docs I was sent.
    Although I normally used NeoOffice for those .docs, Pages would still open any .doc file, but would normally not display it correctly.
    Since installed SL, I've also installed Pages, but not NeoOffice. I want to open a .doc file with Pages, but when I try to do so, I get an error message, which reads:
    Pages quit unexpectedly while using SLCompatibility plug-in.
    Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple.
    If I click 'Reopen', Pages opens, but the .doc file doesn't. If I click 'Ignore' (another button), Pages closes.
    The same error and crash occurs whatever .doc file I try to open. It's not just one file.
    I don't know what SLCompatibility plug-in is, those SL could be Snow Leopard.
    Does anyone know what the problem is and how I can fix it?
    Thanks in advance,
    Jonathan.

    Thanks for the reply.
    I'm running 10.6.2 -- I'm not sure what you mean by 'combo' update, but I updated my new installation of SL yesterday with all the updates that software update could find.
    My Pages is version 2.0.2.
    I deleted the specified file, then repaired permissions, but I'm still having exactly the same problem.
    Some .doc files say:
    Pages quit unexpectedly while using SLCompatibility plug-in.
    Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple.
    Some others say:
    The document "xxxxxx.doc" couldn't be opened
    Do you have any more ideas what's going wrong?
    EDIT: Should I remove the Arial .tff fonts which have minor problems according to Font Book? I don't know much about Font Book. If I remove them, will I still be able to use Arial? I don't want to permanently delete Arial.
    Thanks,
    Jonathan.

    Hi ,
    you can check it in the return codes of the function that caused the error.
    Otherwise, it's a "communication error" - which could be just about everything that can cause a communication to break ,it needs EXCEL to read some info, but EXCEL is closed prematurely. So there is some kind of OLE or RPC communication going on in the background,which should not be interrupted.
    Please check
    Meaning of the SAP return codes:

  • EP Portal "Page Error" when saving address under empployee services

    Hello All,
    We do have enterprise portal for different countries with different role for each country.
    under "Employeeservices ap" role we have different countries like aus , malaysia etc
    when australian employee want to update his address under "Employeeservices ap" role "page error" coming when clicked on save button.
    under the same role , same tab we have diff iviews , but the pagerror coming only when updating address iview.
    under the same role malaysia employee could update the address in the same iview.
    Dont know why it is happening with only one i view and with only one country.
    Please share your ideas.
    Thanks in advance

    iam HR functional consultant , dont much about EP technical side.
    Ah, sorry, couldn't know that
    I'll explain more detailed:
    1. Checking the several Netweaver JAVA Stacks of your components in portal should be the first step. You can do this by going to "http://<host>:<port>/sap/monitoring/ComponentInfo" on your Portal Server and taking a look at the Netweaver Stacks, they will usuall Start with "7.XX' SP XX". The components should all have the same stacklevel excluding Business Packages, XSS Java Components and Connectors. If you are unsure what do to, you should ask your portal guys to update the stacks.
    2. Check whether Business Packages Match with the XSS Java Components and whether the XSS Java Components match with the corresponding Stacks in Your Backend. You can do this using the maintenance optimizer and/or using this wiki which gives a nice overview explanation: https://wiki.sdn.sap.com/wiki/display/ERPHCM/HOWTOGETRIDOFSPSTACKMISMATCHISSUES
    3. Check whether there are any Browser Compatibility Issues (very unlikely..) at https://websmp204.sap-ag.de/pam.
    4. Post the entire log for the error you get. Do this by reproducing the error, then go to "http://<host>:<port>/nwa". From there navigate to "Monitoring", "Protocols and Traces". Select "Default Trace", search for your error, go into detailed View and copy the entire LOG to post it here.
    I hope this is helpful for you now , if you have questions regarding any of that, don't hesitate asking (but please be specific).
    regards, Lukas
