Since a couple of weeks there is a warning in the footer of some of my pages that says like this:

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:1017 - Can't find file: 'mbb_threadviews' (errno: 2 - No such file or directory)
Query:INSERT INTO mbb_threadviews (tid) VALUES('190')

I asume that there is something wrong with my database.

Is there someone who knows where to go to fix this?

Do you made any change on your host ? This error occures when the db file is missing or has wrong permissions. Check that in priority.
If you're using MySQL, you can try to use the repair tool in phpMyAdmin.

Trying to get access to Tools&Maintenance result in following message:

Please contact the MyBB Group for technical support.

Looks very urgent to me.

basically it is a problem with your database server. your webhost should fix it.
