I am fixing someone else's site. Somehow they managed to load modules fro the sites/default/modules dir instead of the sites/all/modules folder. The modules in question show up in the admin/build/modules/list but don't live in the proper folder. How could they have done this? I ask because I want to undo what they did and bring the site back into line with standards so I can fix a host of other problems. I'll figure it out eventually, but if someone could save me some time I would appreciate it!
