Checked the forums today and it seems there is a big issue with Courses Pro. I updated the plugin to the latest version but still issues with the Courses Pro course page is still there. The courses page is not loading and just blank (screenshot): http://i.imgur.com/qBofZFj.png
The unit pages are loading w/o problem: http://vie-epanouie.bonheurenvrac.com/course/vie-epanouie/module/module-1-rever-sa-vie/page/1#unit-page-1
I enabled support access so you can take a look into the problem.
