[Error Message] Plugins List and Settings List can't be displayed

[Krytic]

I'm getting these errors when I try to visit my Settings Page and Plugins Page in the ACP.

Plugins:

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1 - Can't create/write to file '/tmp/#sql_701_1.MYI' (Errcode: 13)
Query:
SHOW COLUMNS FROM mybb_users LIKE 'akismetstopped'

Settings:

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1 - Can't create/write to file '/tmp/#sql_701_0.MYI' (Errcode: 13)
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

In addition, the pane is all "squished up" (for want of a better term):

   

The last two plugins I uploaded were Private Messages Log, and the one that turns a username on showthread.php into a dropdown list allowing you to send them a PM, etc.

Spread to my index page:

This user has been denied support.

Deactivate akismet plugin and delete it
and deactivate all plugins then check if there is an error

It's a problem with your host's MySQL server. Try contacting them.

I looked at my host and they recently installd a new server, so I assume that you're right, euan. Irregardless, it's fixed now, so thanks.
