Thread:Extension talk:MultiUpload/Does not work with 1.18/reply (2)

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.
