So…if anyone else was having that problem with not being able to post mp3’s, it’s working again for me. I don’t know if Tumblr just suddenly got its shit together or if it was this other thing I did—I’d been using the plugin Missing E, and I disabled it and rebooted my browser and it was still not working, but I just rebooted my whole computer and now it is. So, if you use a plugin, that might be the culprit.
Ok, can someone explain to me how to get Tumblr to stop telling me “Only audio files allowed” WHEN I TRY TO UPLOAD A GODDAMN AUDIO FILE? Yes it’s an mp3 and yes it’s under the size limit, THERE’S NO REASON FOR IT TO NOT WORK. God the Tumblr redesign sucks SO HARD.
