Welcome to the Question2Answer Q&A. There's also a demo if you just want to try it out.

The install went alright, but after posting a sample question, I get nothing but a blank page when I click on it.

When I view the source of the blank page, the output is:

<HTML>
	<HEAD>
		<META HTTP-EQUIV="Content-type" CONTENT="text/html; charset=utf-8">
		<STYLE type="text/css">
			body,input {font-size:16px; font-family:Verdana, Arial, Helvetica, sans-serif;}
			body {text-align:center; width:640px; margin:64px auto;}
			table {margin: 16px auto;}
		</STYLE>
	</HEAD>
	<BODY>

This repeats about 10 times.

There are errors in my apache log as well:

(The query keeps going but it is too long to post).

I tried increasing the max_allowed_packet in my.ini to large numbers and the error keeps happening (the apache log showed that error).  Any idea what is going on?

Furthermore, in the admin panel, everytime I refresh the page I get different URL options with the OK label next to them.  This is on a development server and I have rewrite turned on.  I've tried every one of the rewrite options.

Try switching on QA_OPTIMIZE_LOCAL_DB in qa-config.php - at least that will help determine which database query is causing the problem.
