Have you fired up fiddler and see what the payload of the ajax post is? It could be something obscure like a too long url post (or a get not a post) Is the site posting/querying to another domain? could it be some sort of xss thing. (I know you said its posting to the same site, is it perhaps retrieving assets from another site/domain?)
Have you tried another browser, the thinking is mayby if you are on IE, IE received a security patch that tightened some flaw or something which you may of relied on and can't no longer. Tying firefox/opera see if the result is the same.
