On any form submission, redirects to login_url ? Possible causes?

[TheGamer]

Hi everyone,

First off I'm using 2.0 Beta 3.1 - I'm not sure what I could've done to cause this, but now every time a form is submitted, such as posting a thread, reply, or even saving changes in the admin center or your profile, it redirects to my custom $_SESSION['login_url'] which I have had set for a long time, not sure what made it do this all of the sudden...

Any ideas for possible causes or places to look?

Thanks!

Any ideas guys? Sorry to bump

Have you tried this on beta 4 incase this is a known bug that has already been fixed?
