Trying to update from Wordpress CiviCRM 4.7.11 > 4.7.23. Update script does not work. Keep getting the same message:
"Sorry but we are not able to provide this at the moment. Your database has already been upgraded to CiviCRM 4.7.11"
I did everything exactly as described: stayed logged in during the process, removed the complete civicrm plugin, installed the new version, removed cache files, cleared browser cache etc.
Does anybody know what the problem is? I know there must be old files somewhere. But where?
