Hi folks,
I have a strange behavior in wpforo 2.1.7 - https://itgames.it/community/
If I leave the standard links in the menu such as

/%wpforo-register%/

I get the url

 https://itgames.it/sign-up/?redirect_to=https%3A%2F%2Fitgames.it%2Fcommunity%2F 

and as a consequence a redirect to the forum home.

If instead I call the page without parameters:

 https://itgames.it/sign-up/ 

it works.

I have tried leaving only wpforo active but the behavior persists. It was working a while ago, I don't understand what could have changed.

Do you have any suggestions?

thank you very much!
