Visual Editor only working for the admin user

this fixed it.

The Tiny MCE is looking for a file: wp-includes/js/tinymce/langs/en.js

I just checked the file and on my installation the file path is this:
wp-includes/js/tinymce/langs/wp-langs-en.js

I deleted the ‘wp-langs-‘ part of the file name ‘wp-langs-en.js’ and I
seem to be working again.
