Just upgraded to 3.6.8 and have a bunch of hacks, having a profile problem

[ludachris]

I'm having a few users complain that when they go into update their profiles that the information is not being saved. I am unable to replicate the problem in IE or Firefox. What should I look into? Maybe check the hacks that plug in at certain hook points?

Make a list of hacks and post them here, also check those hack pages and see if they are compatable with your vb version, maybe upgrade some of them and see if they work then.
