The owner is "waiting for an update from the developer", so i just wanted to bring it to your attention.

Doesnt work here either. (Windows server)

I have a Linux server and it's working fine here, although it's a bit fiddly to set up with having to install libs and mono etc.

works fine for me and im on a windows server

would you mind letting us know how you got it to work after the update?

already had it installed and it carried on working after the air update.

I've found that using http:// instead of https:// let's me use the plugin normally. For most imgur images, you can just delete the "s" and you'll be good.
