Hello, I'm not a Javascript person so I haven't troubleshot this fully yet.
It looks like when nuModusVersus's behaviour.js is in effect, the frontent K2 editor ceases to function correctly.
Multiple things do not work, such as toggle sidebar, attachment field adding, the "close" button, etc.
Also, I must note that the contents of the K2 frontend editor window spill out to the bottom and right of the rounded modal window that pops up when editing via K2. But this is purely a graphical problem.
I would like to become a paid member but only when I determine if this will be fixed or is caused by something I set up incorrectly. Maybe I need to disable jQuery loading somewhere in K2 or pick a different version of jQuery. I don't know, I fiddled with it a bit. K2 is the only extension I have added to this Joomla 3.2 installation, other than the nuModusVersus template.
Thanks!
