When I try to "Send Private Message' to another user I get this error: Not Authorized To Post I'm using the latest version of Firefox 77.0.1 (64-bit) I've disabled all add-ons/extensions I've cleared my cache None of that helped. The console warns: Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form. The file will not be sent. Any ideas how to fix this?
