Thanks for the heads up! It may be that the filtered query yields no results and I'm showing a blank page instead of a message. I need to add a nice info message like "No results – please remove some filters" or something along these lines to make it clearer.

Try with a common query word like "cat" – filters work fine for me with all models!

It appears the stable diffusion results are being blocked by my DNS adblocker. I turned off my blocker and it's fine now.

Update – just fixed this!
