Update (DID resolve issue)

This forum post: Cant see channels does deal with a similar MySQL issue. I used show tables and found that the mattermost database contains 46 tables, while Ilya’s script only had 42 alter table lines. To save anyone else my frustration, the (4) new tables are:

ProductNoticeViewState
ThreadMemberships
Threads
UploadSessions
Login to MySQL
mysql -u mmuser -p
MySQL commands (including 4 new lines for the new tables)
