bbPress.org

Hi, for some time I’ve got a problem with 404 error everytime I submit a post. (the post is saved but i got bad redirect 404 error)

I’ve tryed to use  Tools->Repair Forums, updating Permalink settings and updating
Forum settings.

I’ve trun off bbpress plugins as well… nothing helps

After submiting, the redirect URL goes wrong. it doubles the “blog”:

https://domain.com/blog/blog/?topic=topicname/#post-1800

or sometimes:  https://domain.com/blog/?forum=topicname%2F#post-1805

Whats “%2F”??

Is there anyone who knwos how to resolve it?
