Uncaught ReferenceError: Z is not defined (line 1)

Author Posts


Since a few month MT got gradually more problems with every update. Targeting now doesn’t seem to work at all. The area where normally the selectors appear stays blank and I get this error message:

Uncaught ReferenceError: Z is not defined (line 1)
Microthemer discovered a JavaScript error on your site:

Error: Uncaught ReferenceError: Z is not defined
URL: /wp-content/plugins/groundhogg/assets/lib/js-beautify/beautify.min.js?ver=5.8.1 (line 1)
Source: Microthemer interface

The MT Preferences page in the backend also stays blank.



It looks like there might be a conflict with your Ground Hogg plugin. You could try temporarily disabling it to see if that fixes the issue. Either way, I would be happy to troubleshoot this for you if you don’t mind sending temporary access details for the site via our secure contact form.



Hi Sebastian,

I staged the site turned off all plugins except Microthemer and even switched to different themes (I use Reign child theme on production site).
Last version of WordPress.
The behaviour of MT did not change.
Still blank settings page, still no way to create selector.
But see for yourself. I created an admin user for you.
