Hi,
@EmigrandOuest at some point of upgrade we probably (not purposely) saved the course under some page directory. So instead of reading of oursite.com/course/cousename it was saved as oursite.com/course-status/coursename
Then the course was showing with all blank spaces, as yours.
You can check if your permalink is saved correctly in Settings->Permalinks->check the right folder
Hope it'll work for you
Good Luck!
@EmiGrandOuest : We tried opening your site but we are unable to access the wp admin pages since your site is running extremely slow.
Can you please check.
It opens normally here. What should I do?
Please find below the required screenshot.
Issue was related to third party plugin, please check above thread for more info.
Closing this.
