Thread:Project:Support desk/Database Error When Uploading New Files

hello there, I've been running mediawiki for about 6 months.. suddenly I'm unable to upload new files. When uploading files, this error appears:

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "IndexPager::reallyDoQuery (ImageListPager)". Database returned error "1: Can't create/write to file '/tmp/#sql_dc3_0.MYI' (Errcode: 13) (localhost)".

Help!
