Hi All,
I just upgraded my wiki to 1.12.0 and used the adepted version of the FileLink-Extension posted here: http://www.mediawiki.org/wiki/Extension_talk:FileLink
After installing it I got no error-messages, but I did not get the extra-button for starting the file-link-"GUI".
In order to find out, if the extension got started at all, I added a line <pre>alert("FileLinkExtension wird gestartet");</pre> right at the beginning of the function addFilelinkButton() in mainfile.js, saved the changed file 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. :)
I hope, posting this here as well in http://www.mediawiki.org/wiki/Extension_talk:FileLink might help people expierence a similar strange behaviour with exentensions.
Regards Katharina
