Wiki Page throwing lots of notices, page not showing

Hey, I went to the phpBB Wiki, then went to Documentation->API, and selected the Parsing Text link ( http://wiki.phpbb.com/parsing_text ) and it began throwing errors & notices. The first one to appear was "Undefined index: serverFile in /var/sites/wiki.phpbb.com/extensions/syntaxHighlightExtension.php on line 94", and it goes on with a table referring to the call stack, as follows:

"Call Stack

1. Time Memory Function Location
   1 0.0000 99336 {main}

   ( ) ../index.php:0
   2 0.0075 1314568 MediaWiki->initialize( ) ../index.php:90

   12 0.1453 3905848 syntaxHighlightingRenderHtml( ) ../Parser.php:0"

That's only the first error, there's a LIST of the notices, each with their own call stack trace.

Seems like they all end with the same file to blame, something called syntaxHighlightExtension.php.

&& – It kept doing it for a while, and now it's working. o.O;;
