Thread:Project:Support desk/Update previous MW 1.16.5 to 1.17.0 throws an 500 internal server error

MediaWiki: 1.17.0 (files), 1.16.5 (db)

PHP: 5.2.17 (cgi)

MySQL: 5.0.91-log

I recently updated from 1.16.3 to 1.16.5 and now wish to upgrade to 1.17.0.

using the new web installer, I was able to get to the point where it upgrades the DB, but it then throws an "Error 500 - Internal server error"

Here is an example of the fact that the DB is not updated.

When editing a page.

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

SELECT iwl_prefix,iwl_title FROM `mw_iwlinks` WHERE iwl_from = '1473' FOR UPDATE

from within function "LinksUpdate::getExistingInterwikis". Database returned error "1146: Table 'db278724580.mw_iwlinks' doesn't exist (db738.perfora.net)".

I already looked at this Manual:How_to_debug and I cannot get the debug .txt file to work. Calebrw 23:47, 27 June 2011 (UTC)
