Thread:Project:Support desk/upgrade from 1.16.1 to 1.21.1 failing/reply (3)

I was able to get 1.16.1 working again by restoring the DB, and remembering to re-enable

AddHandler application/x-httpd-php52 .php

in my .htaccess, which was needed when the host made php 5.3 the default.

I have now restored my DB and started with a fresh set of 1.21.1 files, updated extensions, and my LocalSettings.php that worked with the local copy of 1.21.1 (edited to reflect the host mysql server, etc).

When I run update.php (or rather when my host provider runs it on the command line), I still get the error referencing "Unknown column 'page_content_model' "

My host is about to discontinue support for php 5.2, so we cannot continue to use mw 1.16.

Does the updater care about extensions? I was under the impression that it merely updated the DB structure. If so, why should it fail to update a working 1.16.1 DB?

Any help out there?
