I am locked out of my admin area!
Not sure why, but I am unable to reach the login page. /wp-admin shows a 404 page and /wp-login.php gets caught in a redirect loop.
It might have something to do with the fact that I changed the permalink structure to Post Name, or it might be a plugin problem (Just installed Yoast SEO, which seems to have some redirect instructions), but I was unable to recreate the problem on a test site so I'm really at a loss.
Is there a way to get in and change the permalink structure back to default from the backend?
Any advice would be greatly appreciated.
