In WAVE you to also them click the Styles BUTTON, to remove styles to see those errors when they are in hidden/as-yet-unrevealed content.....

Subject: Re: [WebAIM] checking for contrast errors

on Wave there are 3 buttons on the top Styles, No Styles, and Contrast.
Clicking on the Contrast button, shows the 4 errors.
but I can't find them on the page either.
3 of the 4 errors are the same color combo #000000 and #252525 the last one is #ffeeb5 and #f9f9f9 In your css you define the foreground AND background for most elements.
Given that, still can't find the offending combinations anywhere. One of the things I do to find "hidden" low contrast text is to select all on the page to highlight everything. poor contrast (forgotten heml elements because of contrast) pop out. That is not the case on your page.
I think this is a wave team question
