Hi!

I have been recently hit by the error that says: "Unknown Open Collaboration Service API error. (999)" when I want to install some "New Looks" from Plasma Add-Ons. I am running on Arch 64bit with the newest kernel. I always install software from AUR, but this little error keeps bugging me. When I try to download something from the Discover application, it works, but it shows me 3 Arc Dark themes and Papirus icon theme installed (I previously installed it via Plasma Add-Ons, but I manually removed it, because I couldn't get it out of my PC, because of this error).

I totally can't install any software from this app, because of this error.
