I can't edit any settings on my forum.
When I'm going to settings:



MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1 - Can't create/write to file '/tmp/#sql_1305_0.MYI' (Errcode: 30)
Query:
SELECT g.*, COUNT(s.sid) AS settingcount FROM mybb_settinggroups g LEFT JOIN mybb_settings s ON (s.gid=g.gid) GROUP BY g.gid ORDER BY g.disporder

Please contact the MyBB Group for support.

What can I do?

If it can't write to the database file then upgrading won't fix that.

That sounds like a server issue.
