something wrong with the logout.php..i cant logout stuck on admin acc o my~..someone willing to help?im not good in java btw :):

For what I see it's a Webpage, I recommend as my programming teacher said "Stealing is good", Download a webpage you actually know logout works, and copy the embed code on the Logout.php / or Logout java embed code, you can do that on Notepad++ so you don't get lost. Or just use another webpage.
