MOODLE version: Moodle 2.2.2 (Build: 20120312)
I have installed Bulgarian language pack from the site preferences. When I switch to it everything seems OK except that all the dates (forum, assignments, etc) are in English. Everything else is translated. When I installed Russian or German it is the same - all the strings are translated except the date which is displayed in English.
I turned on language debugging. I find the corresponding date string in moodledata/lang/bg/langconfig.php and added additional characters to test weather the file is used or not. After refreshing the page the characters were visible but the date was still in English.
Any ideas how can I solve this problem?
