Starting with version 1.7, the appropriate place for language files for 3rd-party modules & plugins to reside is the lang folder within the plugin folder. Unfortunately, a number of 3rd-party plugins - which maybe were at some time in the past considered for inclusion in the Moodle core files - are still residing with the moodle/lang/en_utf8 folder. Some of those files are in fact pretty old, useless, and they conflict with the newer, update language files residing in their proper 3rd-party plugin folders
Such is at the moment the case for the Questionnaire module language files in 1.7 and 1.8. However, those files have disappeared from 1.9 and 2.0 (head), which is OK.
Can a developer with the necessary CVS rights please remove all the Questionnaire module language files from Moodle 1.7 and 1.8 (including the help files)?
Thanks in advance,
Joseph
PS.- Maybe the maintainers of other 3rd-party modules want to check for this problem for their own lang. files.
