We had disabled the Hummingbird CDN a while back because it just wasn't working right for us for some reason and switched to using Cloudflares. During WPMUDEV's issues the past few days we noticed our CSS was scrwed up because it wasn't loading from WPMUDEV's CDN. I checked again today and it's disabled – we can't figure out why stuff is sill loading from there. Caches have been cleared several times. Need help completely separating our site from your CDN.
