Just upgraded to the 18.05 version from 18.04

congratulations .. successfully installed

then when I went to the admin page I go this message:

MyBB has experienced an internal SQL error and cannot continue.
SQL Error:1054 - Unknown column '2fasecret' in 'field list'QueryELECT 2fasecret FROM mybb_adminoptions WHERE uid='1'
Please contact the MyBB Group for technical support.

Did you upload all files to correct locations and run the upgrade script?

Yes all files except
inc/setings.php

You're using a custom ACP directory name, of course you should upload new folders/files from the 1.8.5 package's default admin to your custom location.

Also, remove admin folder from your server, otherwise this layer of security is pointless.

You are 100% right

sorry for the problem
