JQuery POST failing with HTTPS on the same server

[ocx32]

I have a strange issue with JQuery 1.6.2 and POSTing to a page on the same server.Error:\[code\]POST https://[phpfile].php 500 (Internal Server Error) jquery-1.6.2.min.js:18send jquery-1.6.2.min.js:18f.extend.ajax jquery-1.6.2.min.js:18f.(anonymous function) jquery-1.6.2.min.js:18populateList main.js:1112(anonymous function) main.js:211e.resolveWith jquery-1.6.2.min.js:16w jquery-1.6.2.min.js:18send.d\[/code\]Situation:This is a Facebook app that will do the common things (note, every release before yesterday was ok, and nothing changed code wise in regards to the files affected). When the app loads it will request a list of friends and gifts based on the user.At first JQuery was causing bugs when linking directly to Google's api page, so the JQuery file was moved to a local folder. Now when we try to use POST, anywhere in the code, we get this error.Can someone shed some light please.Note: Because the error was a 500, I at first thought there may be a problem with the php script. So the script was verified to be in tact and we did sample POST messages to the script directly WITHOUT failing.
