Hi there, may be you´ve stumbled over that issue already and have a solution for that. Everytime a user or visitor visits the wiki-section the first time in his browser session, he receives this error message: Code: Warning: session_destroy(): Trying to destroy uninitialized session in /var/www/vhosts/myhost.com/httpdocs/wiki/includes/GlobalFunctions.php on line 3473 After a reload and the renewal of the session of course it´s gone, but the error message is visible to everyone publicly. Anyone an idea how to solve thatrid of that? Regards, Sperber P.S.: Debug mode is enabled while we develop our site. When disabled the message isn´t visible, as it should be.
