Wpforo cant see Userpanel & register/login Page??

Hi

I have a huge problem:

I have bought many premium addons for Wpforo in the past and hope you can help me with the following problem.

About 2 months ago I disabled wpforo and all addons because I wanted to change the entire page from divi builder to elemementor.

Now that I've rebuilt everything on Elementor I wanted to continue working on the forum page.

the problem is that the Wpforo is displayed but the User Panel / Login / register window of wpforo is no longer displayed, it appears either: "404 error ,, or ,, this page does not exist, ???

what is the problem?

here the link to my forum:
