lakshya As for the first question, I don't know, that's something the developer(s) would be able to answer (AKA. I don't use the extension and I don't know how to answer that).
But I will update all extensions because it has been a while without any update. We're currently a bit busy with different kind of FreeFlarum stuff :)
Edit: We're still on beta.15, so I can't update it at the moment (latest version of the extension seems to be compatible with beta.16 only). That will hopefully change soon. However I'm updating extensions anyways
gabrielpipolo local file upload is currently disabled too anyways. If you want to share same files between forums, I'd suggest to just share the download link from third party service before there is a better upload system for FreeFlarum forums (which most likely won't happen soon)
