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.
@Robin I will follow your recommendations and get back to you shortly. Thanks a lot.
@wpturk Thanks for letting me know. Those errors are SSL errors. Do you think they are related?
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
