I find the problem.. Plugin Elementor Pack. After disabling that plugin registration works again.
I hope this will help someone.

One more question, if I switch to default theme will I lost all settings in the theme currently activated on site? Same question for plugins..

Ok, thanks for advice

I post the same question on wordpress.org and they say: Ask on bbpress..

So, again, when I try to register on bbpress forum on my website after inserting the username and mail and pressing the Register button on https://karate-training.net/wp-login.php I see only -1 in upper left corner.

Did anyone have a similar problem?

Here is the example
