that does not make any sense to me... it is stated in FAQ that index.php filename cannot be changed. Obviously programming logic of XenForo relies upon existence of index.php and its contents in order to function properly. But on the other hand the htaccess can be used to totally disable the system with a DirectoryIndex setting. They are two separate entities and htaccess should not be affecting XenForo like that. This is somewhat limiting is it not?
OK, purged my system, did not mean to offend.
