Can Not Delete digital signature

Acrobat 6.0 Windows. Have a digital signature field (mine) in a document. The digital signature tab and the field both show a red X. The signature tab says the field is invalid. It says it contains potentially malicious content - Java actions. It also says that changes were made to the document that invalidate the signature.
I need to add some more text fields and fill in their values and can NOT do that now.
I have checked the Knowledgebase and the Help file and can NOT delete the signature the way they say - it says the signature is read-only.
Please HELP !

Hi,
It sounds like the document author set the file up so the creation of the signature locked all of the fields in the document (to prevent tampering). If that was the case, then the signature field was locked as well which prevents the signature from being cleared. Sorry, but there is no work around.

  • Deleting Digital Signatures

    I want to delete digital signatures as I've added several trying to get this right.  I've followed the help instructions by going to tools, protection, ,more protection, security settings and there are no digital signatures on the left as the instructions indicate.  How do I delete these extra signatures?

    If the signatures panel says there are no digital signatures, there are none. Perhaps you have stamps/scribbles on the pages rather than digital signatures.
    In any case it is VITAL to archive the file before signing, because you often can't go back.

  • Can Not Delete Event Sent by Organizer

    Ok, I have an odd and annoying problem.
    There are a ton of repeated events in iCal in Dec/Jan (all the same event repeated). I can not delete them as it says "Only the organizer can change this event". Furthermore...
    They are now syncing with the iphone but there is no "Delete" button there (as it was sent by someone else).
    How can I get rid of these?

    Fredrrr,
    According to iCal Help "If you can’t change an event or calendar:"
    "If you were invited to an event, you can change only your status for the event, the calendar where the event appears, and the event alarm."
    Also, read: When Not to Send iCal Invitations - O'Reilly Digital Media Blog, for more information.
    I think that YAI, by John Maisey may be able to help you, but I do not know for sure. If he reads this post he will be able to confirm or repudiate my suspicion.

  • KeyUsage does not allow digital signatures

    Hello,
    I'm getting the security: KeyUsage does not allow digital signatures error (in java log) when trying to authenticate our web-based java app using a smart card (CAC). The smart card authentication works fine on one test system, but not the other. Both are using the same 'certificate' (we believe). Both have the same IIS 6.0 settings, and same java setting...as well as IE browser settings.
    Visually, the symptom presents itself via the sun java login prompt when clicking the link to load the java app. We have an asp client that works fine. Only our java app is asking for re-authentication. If we manually type the credentials of a system admin, it loads the applet fine. What I can't figure out is, "Why are we getting prompted for a log-in to begin?"
    Note: We have verified that IIS (via IIS logs) that authentication is successful, yet still prompted.
    Here is a snippet of the java log: ----------------------------------
    security: Checking if SSL certificate is in Deployment permanent certificate store

    Any clues?

    One of the KeyUsage extension bits is DIGITAL_SIGNATURE which in your case has most likely not been enabled so try getting a certificate signed with the DIGITAL_SIGNATURE bit enabled. It would be a good idea to actual have a look at your certificate to see which KeyUsage bits are enabled and whether the KeyUsage extension is set as critical or not. If the extension is defined as critical, then all the bits have to be followed, whereas if it is not critical, then the bits can be ignored and it depends on the API used on whether they enforce what the bits say.

    You have no choice but to lose your data back to the last backup you made.
    Here's how to do the recovery.  Note you may have to try to get into recovery mode more than once to succeed:

  • I can not delete my history and adding new bookmarks. Upgrading to later Firefox versions and/or re-installing didn't help. The address bar still shows the web addresses of old and whenever I make new bookmarks, it's always gone as if it was never made.

    I can not delete my history and adding new bookmarks.
    Upgrading to later Firefox versions and/or re-installing didn't rectify it either.
    The address bar still shows the web addresses of old and whenever I make new bookmarks, it's always gone as if it was never made.
    Also, I have noticed that every once in awhile you can not close tabs you've opened, either by pushing on the X button and/or clicking on the mouse to close it. Although closing the window and opening it again (without closing the Firefox application) seemed to rectify the problem in the short term, it's becoming quite annoying.
    == This happened ==
    Every time Firefox opened
    == the Firefox is being used

    I think I have a solution.
    First, download the add-on SQManager. This should be included with FireFox, it is really good.
    Look for the file '''moz_hosts''' in the folder '''places.sqlite'''.
    Don't delete the file, just delete the information in the file. My file has over 3600 websites, which go back years!! I did not know they were there, but I was frustrated about not being able to get rid of them. They popped up every time I used the address bar. Clearing my history would not get rid of them.
    This is where they are stored!! I found that by deleting the pesky web site from '''moz_hosts''', it does not appear in my address bar anymore!!!
    I think that if I just delete all the websites in moz_hosts....
    Wa-la...History Gone!!!
    As long as you don't delete the file, just empty it, FireFox won't know the difference. It will just keep adding websites to it until you empty it again.
    Why running "clear recent history" doesn't do this, I don't know. You are doing manually what "clear recent history" is not doing.
    Please tell me if you see any flaw in this.

  • I Can not delete appointment made in Outllook in my Iphone

    Why can I ?
    What is the purpose then to have it sync?
    if you can only dothe change on one side and then sync to have it mirored in Iphone
    Any clue?
    Other question: in my Outlook I have several calendar. When I choose to sync calendars in my iphone, color are picked random. Why can't I choose the color i want in my iphone (why if i want the personal calendar to be green instead of orange? )
    Thanks

    OK regarding the color of the calendar.
    A little trick.
    I create as much calendar in Outlook, and then sync with the Iphone (trough Exchange)until the color I wanted show up.
    example I wanted the Personal calendar to be GREEN
    After test1 + test2 + test3 ........on test5 calendar the color was green.
    I then deleted the other calendar not needed.
    And the test5 colored green was still in place.
    I then rename this calendar to Personal.
    And voila

  • For some reason, I can not delete bookmarks. I did one at a time, then tried 5 or 6 and it worked once then no more. I then tried 1 at a time and it worked once the no more. This is a brand new computer (Win7) and FF just loaded about 3 hours ago.

    # Question
    For some reason, I can not delete bookmarks. I did one at a time, then tried 5 or 6 and it worked once then no more. I then tried 1 at a time and it worked once the no more. Why is this happening? This is a brand new computer (Win7) and FF just loaded about 3 hours ago. Do not know how the bookmarks even got in there. Some were ok, but no order and some that were never bookmarks. Looks like FF tried to import some BM's from the Virtual XP installed, but did not get it any where near right. I need to completely delete all of them and install from a saved .html file.

    Well, I did not see the exact problem that I was having listed in the articles, BUT the problem is solved for now.
    I opened FF and the Bookmarks to Organize again. I deleted all of the folders and entries, ONE AT A TIME, AND IT WORKED. Evidently, for what ever reason, FF did not like "Batch" deletes of ANY amount greater than 1 and the HANG UP would occur.
    Deleting one at a time then importing the good .html from a good file, loaded the wanted Bookmarks. Yea
