[...] after excerpts not working?

My ellipses after my excerpts have stopped working. I'm pretty sure that they were working fine until I tried to customize them and then I thought that broke them so I reset the whole excerpt configuration page back to default (because typing the ellipses back in didn't work either) but still no dice.

I've tried disabling all of my plugins and that didn't solve the problem either.

I am using the latest versions of WP and Atahualpa. http://coloradoanimalwelfare.org/

Thank you for any help!
