I have been receiving increased numbers of "Unsupported URL" when attempting to update numerous WoW add-on's via the curse client. I searched the forums for that and only found one other instance last November of the same issue. Has anyone else been having this issue? One of the add-on's is Recount which is extremely popular and recently updated so I am not sure if this is a curse issue or something else.
If this is still happening, please file a report from within the App. If you're using the v5 Client, you should switch to the v7 App, as the Client is no longer being supported.
I'm also locking this thread, since these forums are for site feedback.
