 * Hello,
 * The plugin work perfectly but have only one (but very problematic) trouble. If
   i use the common.php from Single Sign On, I can’t post on my forum (phpBB3, last
   version), I have an error 500. And if I use the original common.php I can post
   message but I have an error 500 when I add a user on WordPress. Anyone had this
   trouble ?
 * Thanks
