Does not work with 1.18
Nothing new there. The error message also occurred with MW 1.17 and possibly MW 1.16 as well. You can simply ignore it I think.
I've been using this extension successfully with 1.16.5 with no problem. I'm looking to update to 1.18 - I have all the other extensions we use updated and functioning, but not this one.
Yes, the error could be ignored, but it's horribly unprofessional to appear in a corporate document repository. I'm sure I could hack a way to suppress it, but I would rather find a solution that allows the features of MediaWiki to keep working when uploading files.
You're absolutely right, of course, and there's some more room for improvement. Unfortunately, User:Tderouin (the creator of this extension) hasn't shown up to comment on this page. In fact, unless someone is prepared to take over from him, the extension does not appear to be maintained any longer. I don't know why so many useful extensions are being neglected by the developing community lately, but maybe slapping an Unmaintained tag could help to ignite some interest.
Cavila, this might be due to the fact of creating ResourceLoader in 1.17 which supposed to make JavaScript developing easier and it only made it much complicated or even impossible or at least impractical in some use cases (see Bug 27488).
I'm using this extension and I could probably fix it for new versions of MediaWiki but I simply cannot upgrade to the latest version.
