you may have to modify your sql database or reinstall some modules. When we changed our site, the linking broke in a few of the modules we were using until I reinstalled them or found the value in php myadmin where it had taken the IP in order to append it to some of the directories specified in the cofig. Its an error by some module developers, but its not too horrible a thing to fix. (so if you develop a module use the right variables!!)
