Bugged text editor

[Mark1]

Hi,
I got some ''small'' problem. My text editor is seriously  olive.
I've tried deactivating some plugins and nothing changed. I'm using this theme - https://community.mybb.com/mods.php?action=view&pid=164

If you recently upgraded to 1.8.21, this may be the problem.

Thanks for the reply
I fixed it by installing  some different theme that supports 1.8.21.
