Right now, Filter By Type is not working, at all.

The reason for that is, it depended on a Tumblr feature that showed posts pre-filtered server side. This way, it would be fast and reliable. (For example, for videos, you could go to www.tumblr.com/show/videos - now it just shows a Not Found page.)

Filter By Type would then show the posts, and disable the standard Tumblr Infinity-Scroll and replace it with a custom one I’ve written to load the secondary pages so you could scroll down.

Looks like Tumblr removed that feature, for no reason. I’m not sure if it’s coming back, or it is removed for good, just like the Classic Theme Editor.

I’ll see what I can do to work around this, and make it work again, not dependent on this feature. This will probably require a complete rewrite of that extension. Thank you for your patience.

UPDATE: I’ve just sent a mail to Tumblr staff, asking if it was removed or if they are just having technical problems. If it was removed completely, I doubt I can make Filter By Type work as fast and reliable as it did before.

XKit 6 worked in a different way, and it would skip posts, show some posts twice, and would use so much CPU and would take hours to load a few posts, and I don’t want to go that way again. For Filter By Type’s survival, the server-side filtering should be there. I’ll keep you informed about this, and I apologize about it.
