MyBB Community Forums

Hello, I have a problem with the merge system.
The threads on the new forum keep redirecting back to the old forum.
When I try to log into admin panel it takes me to old forum.
If I log in via forum/admin it logs me out and now I cant get back in.
Config was all correct and plugins disabled.
Ive tried different browsers and clearing cache, what on earth is going on?
Thanks

maybe this from your .htaccess

URL would be helpful.

And if I remove the old forum the new one still just redirects.
I dont understand why these problems, Ive used merge for years with no problem, now always problem

^ example forum thread URL ? (with test user account if required)

I fixed it. It was settings.php. It had the settings for the old forum.
