Thread:Extension talk:Parser Fun/Undefined class constant

Hi,

I installed this extension (SVN rev 109140) on MW 1.17, but I end with this error when trying to view a page

Fatal error: Undefined class constant 'FH_NO_HASH' in /media/dev/public_html/wiki/extensions/ParserFun/includes/PFun_Caller.php on line 17

Same with the Download snapshot version.
