[Mediawiki-l] Fixing cyclic links

[James]

Hello

Something strange has happened to my Wiki installation. Any attempt to view 
any part of the wiki results in an error from my browser saying

An error occurred while loading http://www.piku.org.uk/wiki/index.php:
Found a cyclic link in http://www.piku.org.uk/wiki/index.php/Main_Page.

Is this likely to be a MediaWiki error or something strange with my website 
itself? Other parts of my site that don't involve MediaWiki work correctly, 
it's just as soon as I go into the /wiki directory with a browser a cyclic 
link appears from somewhere.

Does anyone have any ideas?

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
