Hello,
When you activate TicketAuth and you go in the page: http://my.host.com/wiki/index.php?title=Special%3AUserRights&user=Bertrand+Gorge
It fails because the "user" is recognized by TicketAuth and it tries to connect.
We suggest the following change to the top lines of the code:
$username = $wgRequest->getVal( 'user' );
$sign = $wgRequest->getVal( 'sign' );
$time = $wgRequest->getVal( 'time' );
if ( $username == null || $username == '' ||
$sign == null || $sign == '' ||
$time == null || $time == '' )
return false;
instead of
$username = $wgRequest->getVal( 'user' );
if ( $username == null || $username == '')
return false;
