Member pages are empty after upgrading to version 12

Dear Support,

I am creating this topic here, because I am getting an error creating the topic on the BP support forum!

—

After upgrading to version 12, all the member pages, such as the Profile, Activity, Notifications, Messages, etc., are completely empty. Before the update, everything was showing without any issues.

I have installed the BP Classic Plugin, but it didn’t solve the problem.

Another issue is that I am getting an “Server Error 403 Forbidden – You do not have permission to access this document” on the Members page

Do you have any idea what the cause may be and how I could solve it?

Thank you in advance!

WordPress and all the plugins are up to date:

• WordPress 6.4.3
• BuddyPress 12.2.0
• BP Classic 1.3.0
• Thrive Theme Builder 3.26
