An error occured with the SQL server:
mySQL query error: SELECT c.*,p.* FROM x_utf_invision_downloads_categories c LEFT JOIN x_utf_invision_permission_index p ON ( p.perm_type='cat' AND p.perm_type_id=c.cid AND p.app='downloads' ) ORDER BY c.cparent, c.cposition
This is not a problem with the IPS Community Suite but rather with your SQL server. Please contact your host and copy the message shown above.
