Error on 6.x-1.1 version for Drupal

I use the latest 6.x-1.1 version for Drupal. It used to work great, but with the latest updates, it's broken. It loads fine, but every time it tries to update information, or if you try to you the filter, the Update button says "error" in red. Nothing besides the initial load works, and there are no javascript errors through the browser. It hasn't been working for at least a week. Also, I'm using the Secure Pages module (and have been since the beginning, even when it used to work), but confirmed that Secure Pages is NOT the problem, as I disabled it to test, and it still didn't work.
