Musescore.com upload not working.

Hey, I don't know if the site is going through some sort of maintenance or what? But yesterday it was down for a while and today when I try to upload it won't let me. I am a Pro user so I shouldn't have an upload limit, but when I click the upload button it takes me to the page and asks me to select a file just as usual. I open the file selector, select a file, the loading bar appears, then disappears and nothing else happens. I've tried dragging and dropping the file as well. No luck. Any help?
