What happens when you try to insert the custom class on a block ? Does the class get added or does it disappear after you've added it to the custom class section.
last night I was actually getting both. I'd try to add a class and it would disappear after I saved. Now I don't seem to have that issue but it's just not working.
The template in question is here page=ct-editor&ct_id=2074
That and like I stated.. when I go to edit the template, it keeps putting a button in there. Something janky is going on for sure.
I just noticed all this (img attached) in the console. I'm sure that has something to do with it?
I'll try that. The button issue: A button appears every single time I go to edit that template. I'm using Chrome and even just cleared cache and all data except login passwords and it still put the button there when I even simply load the edit page.
Not sure why you're having the button appearing but I've deleted it and anytime i go back to edit the content template it doesn't appear again.
Secondly all the deprecated warnings are coming from the wordpress block editor itself. This can be related to other plugins that are active but I cannot say for sure why they are appearing.
