Error: $ is not defined
Source fie: http://demo.phpmyadmin.net/trunk-config/js/sql.js?ts=1282947478
And the page never loads
Actually running custom SQL query seems to fail everywhere but query window.
Okay, this seem to happen on demo server only.
Okay, the problem is probaly in fact that AJAX response includes customized footer again.
This bug was fixed in repository and will be part of a future release; thanks for reporting.
