I truly appreciate your input. I migrated to Moodle 2.6.5. I tried all solutions with no success! I reinstalled all Language packs, re-installed the tinyMCE completely. Also copied the tinyMCE language file in the Moodledata directory:
So far no success!
Is there any language path referencing in the DB for the tinyMCE?
Attached what I see and is very annoying indeed! Any thoughts is highly appreciated!
