Hello Robin.
Thanks for answering me.
I tried both recommendations and nothing changed.
Maybe I should try deleting and reinstalling the plugins?
I also noticed some CLS in the Forum Page
it could be a theme or plugin issue
Themes
As a test switch to a default theme such as twentytwenty, and see if this fixes.
Plugins
If that doesn’t work, also deactivate all plugins apart from bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.
If you cannot do this to your site (say because it is live) then use the ‘troubleshooting’ features of this plugin to let you test without affecting other users
Health Check & Troubleshooting
Then come back
You have problems with HTTPs. With inspect tool I see some mixed content errors.
@wpturk Thanks for letting me know. Those errors are SSL errors. Do you think they are related?
@Robin I will follow your recommendations and get back to you shortly. Thanks a lot.
Hello again, the issue seems to be resolved.
I tried de activating the plugins but it didn’t work.
I erased the website and did a clean WordPress installation.
Then I re-installed the AR Member Plugin and bbPress.
The Forum page now works as it is supposed to.
Thank you all for the support.
