I work at PREPA, Puerto Rico's power utility (government owned), in a dept. WOW! Then there's definitely something missing in this business of digitally distributing, working, and signing stuff. I do probably need to update the one user's Acrobat but mine is newer and I have been told that editing a PDF after a signature shouldn't be allowed anyways.Īny idea why one person can edit the pdf when they shouldn't? The person that CAN modify the pdf, despite the signatures has Adobe Acrobat XI 11.0.18. My version is Adobe Acrobat Standard DC and the other person that has the same error has Adobe Acrobat Pro XI 11.0.12. I also get a similar(maybe exact) message from someone else. When I try to edit the PDF, it gives me the error "This document has been signed and can not be edited". The problem is that one user CAN edit the document for some reason and the other person is asking why. I know modifying the text after a signature is a security concern which is why Adobe doesn't allow it. I have users in an accounting area that want to edit a pdf to add PO's and other numbers after some initial signatures.
