Re: Deep Integration with bbPress 1.0.2 and WPMU 2.8.4a
One thing I question but suspect is not related to this problem is: shouldn’t you be including wp-load.php instead of wp-blog-header.php?
You can search these forums for both wp-load.php and wp-blog-header.php to see which one should be included.
But, you’re only getting a 404 in the Apache error logs? What page is being logged as a 404?
Do you have access to PHP error logs? The blank screen is probably a 500 error, so looking at PHP errors will allow you to see what’s causing that.
