HiThere,

When I go to create an K2 Item (Article), and I click in "Save" or "Save & Close", I got the JavaScript Error in my console: "Uncaught ReferenceError: onK2EditorSave is not defined".

Anyone here have an idea of of what this problem is about?

I already tried disable or change version of Jquery on K2 parameters, but still is not enough.

Thanks!

I already did a temporary fix. I just comented the line: 903 of k2.js

if(K2JVersion === '30') {
// onK2EditorSave();
}

Thanks!

This is not a fix. This will cause your content not being saved. Make sure that you are using the latest versions of Joomla! and K2 and everything should work fine.
