Thread:Project:Support desk/SpecialPages Blank (Fatal error: Class 'LonelyPagesPage' not found in ...)

Upgraded from 1.19.9 to 1.23.1 and solved most of the issues - I think. I did have to reload the saved database and then I ran the database upgrade again.

SpecialPages blank with Google Chrome and HTTP 500 error in Windows Explorer.

Can not find solution to missing or blank "SpecialPages". Put in the error reporting into LocalSettings.php as suggested and get:

'Fatal error: Class 'LonelyPagesPage' not found in /mnt/stor12-wc2-dfw1/588082/700780/www.cefresearch.ca/web/content/wiki/includes/specialpage/SpecialPageFactory.php on line 345'

The special pages appear to be there but no index.

Site: http://cefresearch.ca/wiki

From: http://cefresearch.ca/wiki/index.php/Special:Version

MediaWiki 1.23.1 PHP 5.3.20 (apache2handler) MySQL 5.1.61-log

I still have the 1.19.9 version running and the special pages are there.

http://cefresearch.ca/wiki2/index.php/Special:SpecialPages (note that this is for site called "wiki2")

There was mention to disable extensions but I can not find a page that tells me how to do that? I renamed the "extensions" directory to see if that took them all off-line but no change.
