1.6.18 to 1.8.6 - Unknown column 'canusecustomtools' in 'mybb_moderators'

[Jayfore]

The column should have existed in your database, unless you/a plugin deleted it. That's the definition: https://github.com/mybb/mybb/blob/featur...s.php#L466

Whoah -- that was super helpful, and it will be a good reference for the future!  I ended up needing to refer to this for at least 6 more missing columns.  I ran the queries to add them and was able to proceed thru the upgrade.

Thank you!
