Re: 404 Errors in Internet Explorer Only
There’s little reason to run WP *inside* bbPress and it only makes for headaches. Running them integrated but standalone makes each of them faster and has a side benefit – one can work while the other is down for some reason.
Virtually any of the data you might want from WP can be accessed with a few creative PHP/mysql calls from bbPress. If you let me know specifically what you are trying to do, I will try to help.
