Hi! I have a PHPbb 3 forum, SEO Premod, and today my hosting service upgraded me from PHP4 to PHP5 (not sure it's related to my problem, but who knows).

Now, when I login, I enter my username, and then get the screen that says that I logged in successfully.

Yet, when it takes me back to the forum, I am still unlogged.

I see many of my users still being able to log in and post. But I can't. And I'm the admin. It also occurs to a very limited number of people.

The PHPBB forum started supporting me in trying to figure out the problem, until they found out I had the SEO premod and sent me here.

Any solution you can provide would be appreciated.
