i set the mycred subscription to 30 days test course http://www.ajarnonline.com/lessons/test-subscript-30-days/
but it now shows before taking course "800 Points per 1 month > then when student takes the course the 1hour course duration changes to 29 hours
this test student: dan78 bangkok7*
test teacher: mark78 bangkok7*
That is be'coz you have set the course duration in hours from wplms -> course duration in wplms -> course manager . Or you have added the code (filter " wplms_course_duration_parameter ") for the duration in hours .
There can be only one duration of the course and that mycred subscription duration overrides the course actual duration .
If you just want to give access to the course for 30 days.In these 30 days user can access the course any time (not for just 1 hour ) .
