MEMBER BUGS Just let you know that there is a bug for member username rewrite.
eg;
http://www.xxxx.com/members/username-111.html - the custom header doesn't show with red cross image because of wrong path by 'members/user...'
But,
http://www.xxxx.com/u-username-111.html - the custom header does show.
That setting is from Member Rewrite rewritten in admincp.

ONLINE.PHP BUGS:
In the online.php page, doesn't have online seo rewritten "http://www.xxxxx.com/online.php?order=asc&sort=username&pp=20&page=1"
"Unknown Location" /forumname/t-threadnamehere-105.html. Will you fix it?
P.S. Great hack, don't have any problems.
