I am not able to save changes to text field properties in some of our forms. The main error I get is: " The file may be a read only, or another user has it open. Please save the document with a different name or in a different location." No one else has the form open. I've tried renaming and saving in a different location. There was no change. It has nothing to do with security settings on the file. I've tried making the changes on other computers and get the same error. The fields are not read only or requied, either.
Hope you are doing well and sorry for the trouble.
Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check.
What is the version of the OS and the application you are using? To check the version of the application go to Help > About Acrobat and make sure you have the recent version installed. Go to Help > Check for updates and reboot the computer once.
What are the steps you are doing to make changes to the text field properties? A small video recording of the same would be very helpful.
