I am facing an odd problem. My forum was working fine until I uploaded avatar images for some users. I have 4 test forum users, now the users with avatars can't login anymore, it redirects me to the login page, with no error message. I go back to the forum page and I am not logged in.
I even created a new user (without avatar), I logged in and out several times without issues, once I loaded an avatar image I could not login anymore.
My forum is already online so any help will be very appreciated since this is preventing me and other users from using the forum.
Best,
