Adobe DC editing a Fillable Document

[Therese5E99]

Can anyone tell me how I can modify a document that currently has Security and is a fillable form?  I am the author of the form, I created the document, own the Security applied to the document, created the "master password", and there are no signatures involved.  I used to be able to use File > "Save a Copy" and that Save a Copy document allowed me to remove the security and edit the form and republish it for use. Now I don't even see " Save a Copy" option under File and there doesn't appear to be any way around that. I current have Adobe DC Standard.  Forever grateful for any help you can provide.

What happens when you remove the security?

The Save a Copy-command doesn't remove a security policy! It only removes the Extended Reader Rights, which is a kind of digital signature. To remove a policy you must go to File - Properties - Security and select the "No Security" option. Of course, you'll then be asked for the password used to secure the file.

I tried your suggestion and I receive a pop up stating:  You cannot change security on this document because the document is signed or certified.

I've also tried Tools and Protect, Advnaced Options Remove Security and get the same pop up.

Is the file digitally signed?

What can you see at File > Properties > Security ?
