Bug with MediaWiki 1.11.0
I installed and used the FileLink-Extension with mediawiki version 1.10.0 without problem, but after upgrading to version 1.11.0 I get the following error message whenever I try to edit a page.

Detected bug in an extension! Hook filelinkDo failed to return a value; should return true to continue hook processing or false to abort.

Fix for 1.11.0 +
Every function which is registered as a MediaWiki hook must return something so just add TRUE to any Return ;


 * Thanks for the tipp - after I added a true to the one and only return I could find in extensions/FileLinkExtension.0.2/FileLinkExtension.php and also added a return true; to the end of the file/function I don't get the errors anymore, but neither do I get the filelink-button in the edit mode. :(


 * Does anybody have an idea how to fix this?

Fix for 1.12.0 +
This version of FileLinkExtension.php works with mediawiki 1.12

 * Hi Mitchelln,
 * thanks for posting the adapted version for mediawiki 1.12.0!
 * After installing it I get no error-messages, but I do not get the extra-button for starting the file-link-"GUI". :-(
 * Can you (or anybody else) give me a tipp how to debug this? Thanks!

 * Hi again,
 * I don't know why (or how in detail), but I managed to solve the missing-button-problem myself:
 * I added a line alert("FileLinkExtension wird gestartet"); right at the beginning of the function addFilelinkButton in mainfile.js and when I started to edit an article the alert-box and(!!!) the button appeared!
 * And - curiouser and curiouser - the button still appears, even though I commentet the line out, so the alert-box doesn't appear anymore. :)
