I followed instructions for changing the language set to allow "courses" to be called "projects", ie
downloaded en language folder to home pc
renamed to en_project
modified moodle.php so that every occurence of course was relaplaced with project
uploaded en_project to lang directory
set default language to en_project
It did not result in any change to titles on main page. All references to course are still there.
Did all usual - clear cache etc
Is there something else I need to be doing?
Language names must be 5 characters or less ... try en_pr
