Hi Jesse, thanks for the help! It seems to work in post now, but the gif doesn't play when it's a featured image - any help there? Also, how do I access the .htaccess file and where exactly should that line go?

I'm having this same issue as well and I keep getting an http error. I've tried to contact my hosting provider but they weren't able to do much other than do something with the php.. although after he did this I was able to upload the gif into the media library, as soon as the gifs upload, they don't play. I've also tried uploading them into a portfolio post and they also just show up as static images. I've tried to change themes as well and nothing has worked. Do you have any sort of support line that I can talk to to fix this?
