Comment (by hptccharge):

 Replying to [comment:10 westonruter]: YES! Turning off syntax highlighting
 in my user profile allowed me to edit and save the custom CSS. After
 removing the errors, I confirmed that I could turn syntax highlighting
 back on and the Custom CSS was now editable and savable.

 Thank you!
 > @hptccharge  Can you go into your user profile and try turning off
 “syntax highlighting” to see if the issue is specifically with CodeMirror?
