File uploading is not completely broken. But sometimes certain files just won't upload.
I said files and not filetypes for a reason: I had a problem earlier where I couldn't upload a specific .mp3 file, but had no difficulty uploading another .mp3 file.
Earlier on I couldn't upload flv files, but I fixed that problem by using a Mime Editor plugin for Wordpress I had hacked for use in MU.
But now when I go to upload a specific .flv file wordpress won't let me. The oddity here is that I don't get any errors, as I did before when I hadn't been using the Mime Editor, about the file not meeting the security guidelines.
The uploading pane just refreshes as if I had never sent it a request.
Any ideas?
