[Mediawiki-l] Lost pages

[Graham]

Hello,

There is a Wiki that has approximately 25 menu items on the main page, 
and one of the menu items lost the content of the pages below it.  
Therefore, if you click the menu item, the page displays the pages below 
it in red text. The owner of the wiki indicated that he had access the 
pages a couple of days prior to noticing the loss.

I've checked the wiki for records of the pages existing and had no 
success. There was also an extensive search in the database backup, and 
there was no trace of the pages ever existing. It is as if the pages had 
never existed. However, the owner indicated that he did save the pages 
originally and had accessed them on many occasions.

I would appreciate it if someone could shed some light on this.

Here is the configuration:
MediaWiki 1.11.0
PHP 5.1.6
MySQL 5.0.77


Here is part of what the wiki text looks like for the page is question:
=== [[Registration:ReportCalendar|Registration Calendar]]  ===

Year break-down of what-happens-when, including reports to be run.

=== [[Registration:Law|Law Registration Notes]]  ===

=== [[Registration:Error Reports|Registration Error Reports]]  ===

=== [[Registration:Clean Up|Clean-up Reports]]  ===

=== [[Registration:Status Codes|Registration Status Codes - Adding, 
Dropping & Auditing]]  ===

=== [[Registration:XY|X/Y-Course Registration]]  ===



Thanks,
Graham
