Hello People,
I’m having a similar problem here. I tried most of the uninstalling plugin hints, also the cache cleaning, different browsers etc. but no success…
The theme preview doesn’t work, neither does the customize. Mine is a bit worse because the customize also doesn’t show the options on the sidebar. Apparently it happened after the new update.
It only displays:
-“Save and Publish”
-“You are in customizing”
-“Active theme”
When I click inspect element over the preview area, I get this message in the console:
” Uncaught TypeError: Cannot read property ‘get’ of undefined
customize-nav-menus.js:2011 “
The 2011 line is this:
“element.set( navMenuLocationSetting.get() === control.params.menu_id );”
I’m quite a noob on reading and changing wordpress code, but I can follow detailed instructions…
Any chances you know what’s happening?
