Hmm, they should be enabled. I must have done something wrong.
I configured it wrong and the site was expecting webm and pdf files to be images it could thumbnail. It should work properly now.
Thanks, based Seisatsu. As always.
Sei, do webms no longer open inline ? (They open in a new tab in my browser)
Yeah, this started happening at some point and I'm not sure what caused it. I'll try to figure it out.
