Ok, looks like you've checked off all the basics which is great. I don't have much experience with potty issues - but just thinking here... how about instead of the crate, can you enclose her in a certain area with gates? Like baby gates or something, in a safe area of course... no toys, etc. (Like the kitchen maybe?) -- I'm just thinking maybe its the crate itself? Just thoughts. You can leave the crate there too within the area, and open... just to experiment & see?
