When using compression icons break
when using compression the name of the icon file becomes something.min.js but the code expects something.js so all the icons appear as "NOT FOUND"
I have the same problem but in my case it's the theme that it can't find. Exactly the same issue: the frontend requests theme.js, but in the static files on the server there exists only theme.min.js
I had the same issue, but found that putting 'suffix': '.min', in my TINYMCE_DEFAULT_CONFIG in settings.py solved the not found errors when compression was turned on. This should probably be noted in either the documentation, or the suffix should automatically be configured when using compression.
