“Sorry, you do not have permission to access this page.”

Hello,

I just installed the plugin in version 2.0.7 on my WordPress v6.0 site, activated it, and tried to create acronyms. When I visit the overview with all acronyms everything works normal but when I try to create a new acronym (both acronym and full text are entered) and click on “Add acronym” an WordPress error page appears that says “Sorry, you do not have permission to access this page.” (translated from German to English).

I’m using the plugin with the default root user. Permissions haven’t been changed on the site, so it’s the default setup.

To ensure that, it isn’t a WordPress v6.X conflict I tested it also on another site running on WordPress 5.9.X. On this site, the same issue occurs as described above.

Thanks in advance for your help!
