I'm trying to get rid of the security password for a pdf. I went into document properties, security, then change settings next to Security Method. From there, I tried to unblock the box for a security password, but when I went to save the changes, it gives me the following message:
To apply security settings, please set either a Permissions Password or a Document Open Password.
To remove password security, first click Cancel in the Password Security Settings dialog, and then in the Document Properties dialog set the Security Method to No Security.
So, I went back to the Security Method, but I cannot change it to NoSecurity. The box is grey and locked on Password Security.
How do I get rid of the security password in this case?
