We don't know what your database details are if the ones you're giving don't work you'll need to check them with your host.
Quote:MyBB has experienced an internal SQL error and cannot continue.
SQL Error:
2006 - MySQL server has gone away
Query:
DROP TABLE IF EXISTS mybb_forumsread
That is the error I got when I switched from MySQL Improved to MySQL.
Nothing we can do about that, lost connection to the MySQL server.
I'd find a host other than 000webhost if I were you, they're riddles with issues.
When I went to the forum, it asked me to install a new version. It works now, so thanks.
