Sallymelek Resolved. I've connected to your server, taken a backup of the database (in case), and removed the column in question
Once logged in, you'd need to execute
This lists all of the databases present in the system
This selects the database in question
ALTER TABLE `users` DROP `PMSetup`;
This command drops the column needed
I then ran into this
So, we need to drop this column also
ALTER TABLE `users` DROP `unread_messages`;
The migration now completes successfully
kyrne/shout has been re-enabled
I've not enabled the "Let users make their own password - SSO Compatibility" as I don't want to impact any users on your forum. I'll leave that part for you.
Let me know if you need any further assistance.
