Coursepress pages loading forever

Hey guys,

I have a big issue since the last update of coursepress pro. All the site is loading forever (pages, posts, dashboard, courses etc).

I tried to change the theme, deactivate all plugins, refresh permalinks etc but nothing works. Im using coursepress theme.

When i deactivate coursepress pro, everything works again. I have this issue on my subsite

Please try to help me asap on this one ! (access already granted)
