Description of my issue:
I've recently upgraded from Joomla 2.5.11 to 3.1, but this issue also existed under 2.5.11.
It is modules only that I can't save any changes to, and, when I try, the system locks them out.
I checked almost everywhere, including permissions, but to no avail.
I don't know whether it is related, but Firefox throws the following (among other, mostly back-end CSS-related) warnings:
Warning: Empty string passed to getElementById().
Source File: http://domain.com/media/jui/js/jquery.min.js
Line: 2
I'd appreciate any help.
