Hello. This error occurs when I try to open one of my courses on my moodle website. As I understood from some posts, I need to update my website. However, I am not sure how to do it safely and afraid that everything could be deleted. If anyone can help me, please let me know. I am not so good in moodle platform and it would be great if you describe everything in details (how to make a backup of everything etc.) Thank you!
