No offence meant by my previous post, sorry if you where offended!
The index.php which comes with vBulletin, should be left unmodified.
If you have been making changes to the index.php, please re-upload the index.php, found in the vBulletin .zip file, in the "upload" folder .
If you use the original index.php file from vbulltin, it should also fix your "www" error.

What i modified in the .php was unmodified.
Seems that didnt help me at all in the first place...
