I’m having issues with inaccessible admin after each WordPress upgrade. What happens after inserting the admin credentials is the page reloads with the following url:

https://www.website.com/wp-admin/upgrade.php?_wphttp_referrer=%2Fwp-admin%2F

It seems that the issue is caused by a difference in the database version number. I’m updating wp-include/version.php to force a match to the database’s version.

It can be fixed only if I change the number on both places (phpMyAdmin and versions.php file) to be the lower number.

This happens after every WordPress upgrade for the past around 3 upgrades as far as I remember. I haven’t changed anything before that started happening.

Any helps is greatly appreciated!
