Last Update broken my page editor

Hi.

First, I will say I love this plugin, but after I have updated to the last version 1.5.6 It has broken my editor, in the wp-admin.

The editor doesn’t load… It happens when I create/edit any page and also when I create/edit a post.

It has always worked perfectly, but the last update has a bug, that makes the error

Here a picture of my site, when I have the plugin enabled.. https://ibb.co/XJ0Mzkr

and here is a picture when the plugin is disabled. https://ibb.co/mDtFMcg

Hope you have a fix ??

Thanks

Thomas
