Hey there,

I just updated the plugin which has been part of my back office for years, so thank you!

However, since the latest version the syntax colouring doesn’t load. I am using the Classic Editor, if that helps.

Here’s the JS Error I’m getting which does look related:

Uncaught TypeError: 
Cannot read property ‘getEditorMode’ of undefined at 
Object.isGutenbergVisualActive 
(hesh.js?ver=2.3.0:1)

If you need any more info, just ask. The plugin was working yesterday and I’ve added no new plugins/themes today, so this has just happened since I updated.

Thanks!
