Hi!
It was a yet unknown bug, but on the compatibility settings panel I changed the javascript source to “Minified” from “Minified scoped” and the errors disappeared (both from the layout and the javascript console)
I’m not sure why it’s happening, but I will try to investigate this further and upload a hotfix to codecanyon as soon as I find the problem.
Thank you for the proper description of the problem and for the proper log-in details!
