It is most likely a network error of some sort that corrupted the download of WP core. It could also be a poorly configured server that caused a timeout and subsequent corruption of one of the most common WP actions.
Your host should have a backup system to allow you to simply roll back and try again. If they don’t, you might want to consider a decent host. Free backups should be included in hosting these days, much like free wifi in a hotel/airport/restaurant.
Try a manual update. See https://wordpress.org/support/article/updating-wordpress/#manual-update
Thanks Sean & Steven.
Steven, I’m going to attempt the manual update now, but I have another question.
Step 3 tells me to deactivate plugins, however I am not able to access my WP admin to turn them off.
Do you think this will cause issues?
So I found that hitting the restart button inside of Azure app solved the issue.
Who knew turning it off and on again would solve the problem 🙂
Thanks for your help.
