Not presenting logged in user as logged in.

I've been trying to get phpbb integrated with Drupal.

Sometimes, when I go to the front page of the site (http://thetriton.com) it treats me like I'm not logged in. When I hit the login button to login, I get a forbidden error because I'm logged in. Things were very bad where the site would fail until I changed the settings.php attribute: $base_url and domain. However, when I changed it the site crashed and I had to restore from backup which only took a few minutes. I also changed meta redirect to immediate redirect in the drupal configuration admin panel.

Now it will present me as being not logged in until I refresh the page -- then it's normal again, which is a big improvement. So it's not a huge problem. I think that the site might become very busy and would like everything to run smooth now.

I can also recreate the problem because the pattern is that it happens (mostly -- there is not much rhyme or reason to it) after a form is changed in either the admin section, profile, or node edit form. A. I change a form and save. B. I click on the home page. It does not show me as logged in. C. I reload the page and everything is normal again.

I will be happy to submit all the configurations if you think that it will help diagnose the problem. I don't know, but will it be a security issue if I post it here?
