I'm having a problem with Attachments in YAF editor. When the attachment icon is selected, the popup doesn't list existing attachments,, but shows "internal server error" above "upload new files". However, I can still upload and use new attachments.

It appears that the POST to …/forum/YafAjax.asmx/GetAttachments is giving HTTP 500 error; the detail of the error is
"System.InvalidOperationException: Request format is invalid: application/json; charset=utf-8.
at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters()
at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()

The web service appears to be fine with XML requests, but is rejecting JSON requests.

What have I got wrong in my web.config?
