I have been notified of a spelling error in the Welcome Email sent to students when they first log into their course. The "Send course welcome message" is checked so my understanding is that it is the Language string which needs editing.
I have gone into Language customisation and edited the String Core > Moodle.php > string = 'welcometocoursetext'. I have then saved and purged caches, enrolled my test student in the course, however the old message is still sent.
Is there anywhere else that i may have added this message that could be overriding the updated email message?
