I have tested all of the other plugins I am using, and the issue seems to come down to Simple Fields.
When I try to upload media through a post, I get a "An error occurred in the upload. Please try again later." message. When I deactivate the plugin, all is well again and everything works.
I am running the latest version of Wordpress 3.6, and Simple Fields 1.4.2.
