I faced with Issue deleting courses. I cannot delete the courses. I followed the this process to delete the course - Site Administration|Courses|Manage Courses and Categories | and be selecting the course and hit the delete Icon to delete the course , but it comes with this error "error/error_opening_file. More information about this error" yes its passed the 24 hr grace period.
Even when clicking the delete icon, on the delete prompt screen, the "Delete" button is Grayed out...
All the courses are created by the user I am currently login with.
Anyone got a fixed for that. appreciate
