Re: Internet Explorer trouble
Several of initial questions:
1. Have you tried switching back to the standard BuddyPress home theme? If not, do so and see if the problem still exists.
2. Have you tried deactivating all 3rd-party plugins to see what happens? If the problem goes away, you should then reactivate the 3rd-party plugins one at a time, testing after each reactivation to see if the problem has returned.
2. Are there any errors in your log files? If so, what are they?
