Every upgrade is unsuccessful. It takes a lot of time to deal with upgrade issues. For example, there is no backup when upgrading the database and there is no backup when upgrading the site configuration. The upgrade procedure was not done properly. It’s really a trap. It's better not to upgrade. I wonder if you have encountered similar problems?
Every time I use the upgrade, it pops up automatically again. Waste of time dealing with this issue
This issue should be taken seriously
