Well, that Logout part doesn't make much sense for me. If you make a good logout page, all sessions should be destroyed, and there's no way the user can take back his account unless he logs in again.Here's the basic logout:

<?phpsession_start();session_destroy();echo "<meta http-equiv='refresh' content='2;url=index.php'>"; //Go back to the index page?>

At least that one works fine for me

By the way, If someone is reading your page in a different language and they want to translate it, then it will be impossible for them to translate the page except the homepage. Best go with default URLS instead of encrypting the URL.
