FIle Editor is unusable at all with RTL language
I've already sent you this "idea" 2 years ago and this bug doesn't get fixed.
When you set your plesk language to any RTL, the file editor changes all text direction to the right. Which makes it impossible to edit any file. Its not supposed to be a feature, but a bug that must be fixed ASAP.
