Page doesn’t load even after ten minutes?

I have enabled mod_rewrite on one of my two WordPress installations on a certain domain since I want WP to create the links which would remind people of the articles’ names….yet, I cannot even load the page after ten minutes. I guess this has something to do with timeouts, but I’m not exactly sure what to do…the second installation works properly. It had the same problem before but a friend of mine fixed it. Yet, he’s not here at the moment so I can’t ask him again how to fix it and make the page load normally….help?
