Trouble running MailNotification extension
This is a great idea for an extension. Thanks for releasing it!

I'm having some trouble getting it running. After installing, when I submit changes to the wiki, I see this Fatal error: Call to undefined function wfquery in /home/.author/leedh/lee.org/w/extensions/MailNotification.php on line 36

When trying to look at Special:Version, I get this: Catchable fatal error: Object of class MailNotification could not be converted to string in /home/.author/leedh/lee.org/w/includes/SpecialVersion.php on line 241

Any ideas? I'm running --Gadlen 05:20, 25 March 2007 (UTC)
