I am receiving a strange error when visiting my MediaWiki page

Error in fetchObject(): Can't find file: 'page.MYI'

(errno: 2)

Backtrace:

* GlobalFunctions.php line 450 calls wfBacktrace()

* Database.php line 520 calls wfDebugDieBacktrace()

When you are experiencing this issue, this means that your database is corrupted or is missing tables. In this case, you have to make sure that your database details are properly set in the MediaWiki configuration file. If they are OK but you still get this error, the best solution would be to restore your database from your latest backup.
