Unable to change passwords after owncloud > nextcloud migration


I have upgraded our Owncloud 9.1.2 install to Nextcloud 10 to Nextcloud 11. Everything seems to be working fine however we cannot change passwords for users. When we navigate to the users section under the admin account and try to change a user’s password a red banner appears stating if you change the password the user will lose all their files. If i try to apply a new password anyway and press enter it doesn’t change it. I thought maybe it was related to encryption so i removed encryption via command line and the error still happens. How can this be fixed?



Update: Tried command line and this is what i got.

root@nextcloud:/var/www/nextcloud# sudo -u www-data php /var/www/nextcloud/occ user:resetpassword tdale
Warning: Resetting the password when using encryption will result in data loss!
