I have a form with several sections to be signed. The form is in a SharePoint 2007 library, web enabled, and I cannot open it in SP, but I can if I open it in the client. On one of the sections, it was apparently digitally signed just an hour or so ago, but it has the message "There is a problem with this signature" and when I look at the details I get "Invalid signature - This signed content or this signature have been modified" with a box with an X and area for purpose for signing this document which cannot be modified. I need this signature to go away so the form can move on (it's a routing form, and there's 3 other department to get it after this one). How can I fix this form to make it open again in SP?
Updated: I found where I can delete the digital signatures in error so that much is dealt with, so now my question is how do I find the root cause of the invalid signature?
