jQuery και drupal

[jonhh]

καλησπερα,

 

Στο drupal Site που φτιαχνω η εκδοση του jQuerry ειναι η 1.6

 

Αγορασα ενα template που εχει μεσα ενα jq που μαλλον αποτι καταλαβαινω ειναι διαφορετική εκδοσης με αυτή που υποστηρίζει το drupal.

Επειδή δεν ξέρω τι να πειράξω, μπορεί καποιος να με βοηθήσει ??
