I don’t believe this is generally an issue for most who have purchased, but I feel for completeness that it’s also important to add that I have also encountered this error myself, with no local results so far in remedying it since my installation of the theme last weekend.

For myself, I believe it began roughly 2-hours into my becoming accustomed to the new theme options with the advanced-editor, as all was working fine, and I can only assume then stalled after simply updating one of my pages, but I didn’t actually notice the non-functioning javascript until a bit later on, when attempting another page edit, as the popup window for the “advanced-editor” no longer appeared when clicking the button to enter that editing-mode, although the button itself does visually switch from “advanced”, to “default” when selected.

I can verify that this state remains as well even with the removal/deactivation of all 3rd-party plugins I have installed, the deactivation of all page-widgets I routinely have in use, as well as browser, and wordpress cache-cleaning. (*To note, the issue remains regardless of using FF/IE/CHROME, and a fresh reinstall of the latest, updated version)

Also in regard to assisting with any troubleshooting, and just as fm005 states in his post, all other elements of javascript (both theme-integrated, and wordpress-centric) work flawlessly, and without incident as always.

Again, this appears to be a very small use-case in regard to the other issues, if any at all, that users are experiencing at this time, but thank you to anyone who may have a possible solution for us to explore here.
