I have fillable PDF forms with digital signature fields on SharePoint. People are filling it out and adding signatures. For the most part everything works fine. Sometimes however some PDF files are having the following issues:
There is an error message on open: This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document.
Some fields that were previously populated disappear.
When I try to print it I get the message: The Document could not be printed. And when I click ok: There were no pages selected to print
When I go to the signature panel and open the last signed version everything seems to be working OK (fields are there, I can print, no error message).
Any idea what is going on and how to fix it? Thanks!
