Extension talk:AuthorInfo

In AuthorInfo.php I needed to change the 6th line:

$wfAuthorInfoPath = $WPI_URL. "/extensions/AuthorInfo";

without the $ before WPI_URL the path to the javascript was wrong so the extension failed.

Help implantating please
I don't understand where exactly I'm supposed to add  Please advise!!!

Mediawiki 1.19 & 1.20
Doesn't match with Version 1.20... Sorry


 * Doesn't work with MW 1.19. Code seems completely outdated. Would love to see it being revised for MW 1.19 --Stefahn (talk) 22:14, 22 March 2013 (UTC)
