This question may be related to a resolved thread.
Try to upgrade from ee213 to ee221. It failed. The notice is:
A Database Error Occurred
Error Number: 1142
There seems to be a solution:
“After giving the ‘Manage Indexes’ permission to my MySQL user, it seems I was able to upgrade successfully. Now I’m unable to login and have encountered another error.”
I use phpMyAdmin to manage the database. I don’t find, where to Manage Indexes.
The mysql-documentation about permissions is a little to complicated ... Perhaps someone could give me a hint?
