Hi Sebastian,

I’m testing WP 5.6 beta1 (with the Gutenberg plugin activated among others) and Microthemer is giving me this error when using the drop down menu (suggestion – the 3 vertical dots) and any property, for example in the Dimensions section, the Width of the selected target:

Uncaught TypeError: Cannot read property ‘menu’ of undefined (line 1)
Microthemer discovered a JavaScript error on your site:

Error: Uncaught TypeError: Cannot read property ‘menu’ of undefined
URL: /wp-content/plugins/microthemer/js-min/microthemer.js?v=6.3.3.2 (line 1)
Source: Microthemer interface

Note: I did not test this on a WP 5.5 site, nor on a live site, just on a WAMP running Php 7.2x. As it is 2 am right now here in Los Angeles, I will do more extensive testing tomorrow, disable plugins, testing on other sites, with WP 5.5, etc… and try to find if a plugin etc… is causing this.

Once again,
Thanks.

Thanks for the heads up Nick. I was able to replicate this with just MT and WP. It looks like the beta uses a slightly different syntax for referencing custom jQuery UI autocomplete widgets. It now expects a dash (“-“) in the name. I will add a workaround for that.

I hope you managed to get sleep!

All the best,
Sebastian

OK, MT version 6.3.3.3 should fix this issue. There may be other issues if the beta uses a newer version of jQuery UI. But I haven’t noticed anything myself yet.

Thanks again for the early warning 🙂

Hi Sebastian,

MT V 6.3.3.4 which I just received fixed the issue. I have to admit, that was fast, too fast in fact.

Once again,
Thanks a million.
