When trying to upload an audio file to one of the wikis using the /Special:Upload site, I'm getting the following error:

".ogx" is not a permitted file type. Permitted file types are png, gif, jpg, jpeg, ico, pdf, svg, odt, ods, odp, odg, odc, odf, odi, odm, ogg, ogv, oga.

I can update other ogg files already uploaded, however.
