I successfully installed SugarCRM on our virtual server, and it is running fine. But we're having problems everytime we choose a table then click on either contacts, opportunities, leads, etc., the page will load but after that the tabs do not move anymore, and the links don't work too.

I'm thinking this is most likely a javascript error, but I checked if there are errors, but there are none, so if anyone would tell me what the problem is and how to solve it, I would really really appreciate it.

Thanks in advance.
