I'm posting this question as I'm very frustrated with Drupal and I have no idea what to do next.
I've tried everything and I can't seem to find the reason behind this problem.
We are a team of developers that worked on a sports website called http://epikoo.com (Dupal 6 core) and since yesterday the site started to behave very slow.
All the inside pages are loading extremely show. The main page loads normal but if you hit any other link it takes forever to load.
I cleared the cache, rebuild permissions, flushed the image cache, restarted the server...
This site was up and running for more than a year and there was not code changes in the last 3 months. How is it possible to behave like this?
If I login with the Admin user then I can load the pages without any problem...
I'm hoping maybe someone else had this problem before and could at list point me on the right direction.
