I noticed that there is a bug in front end course editor. For example, if you have two categories selected that for a given course you created in WP Admin then you later save the course in the front end you will find it only saves the primary course you see in the front end. I think the reason for this is the front end does not show having the ability to save more than one category.
Also noticed that these URL's are not SEO friendly like most of the others
http://mysite.com/course/course-name/?action=curriculum
http://mysite.com/course/course-name/?action=members
http://mysite.com/course/course-name/?action=events
Notice the URL paramenters left in the URL like "<span style="line-height: 1.5;">?"</span>
Right now only one category can be selected on the front end course creation as of now .
We will be fixing this in the next update of wplms front end edit .
About the link issues in course ,
We will be adding this fix in the next update of wplms theme (version 2.0).
What I am saying is that there is a bug. So if you have two or more categories already selected using the WP admin from backend. Then later you do anything to update from the front end and save it will delete the other categorizes you had selected and only leave you with one. Therefore the frontend is not usable until this is fixed or it destroys all your work of selecting you did on backend.
Yes we are aware of that but i am telling you only one category will be selected in the front end editor so if you ave the course from front end then it will pick up only one category out of many categories that was assigned to the course .
For multiple categories please create a feature request for this here :
