Wikimedia Bugzilla is closed!

I have setup my wiki so that only logged in users can see and edit pages.  This works nicely for all pages  i used :
$wgGroupPermissions['*']['createaccount'] = false;
$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['user']['edit'] = true;
$wgGroupPermissions['*']['read'] = false;
 
# But allow them to read e.g., these pages:
$wgWhitelistRead =  array ( "Main Page", "Special:Userlogin", "Wikipedia:Help");

This works exactly as it should for all pages but the mainpage.  nobody can edit this page, not even sysops.  

even if i allow set the edit permissions to true for everyone this remains the same, sysops cannot do anything on this mainpage, nor can any other user.

I really need to edit this page, so any help will be greatly appreciated,

kind regards,

H
