Map Page shows blank in live view

In live view, map is blank but google navigation tools are shown but do not work - i've double checked all instructions and can get nowhere on this issue.

when a page displays blank in the browser, it is a sign that a php error is occurring but error reporting is turned off.

Add the following code to your page at line 1 to turn error reporting on:

<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>

you may need to view source on the page in the browser to see the error.

"The website needs a different Google Maps API key.." Having done that to no avail, what do I try now.
tnx

make sure there aren't 2 instances of the line that sets the api key:
<script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAvZMU4-DFRYtw1UlTj_zc6hT2yXp_ZAY8_ufC3CFXhHIE1NvwkxQcT1h-VA8wQL5JBdsM5JWeJpukvw">/*wagmp*/</script>


When generateing the api key, make sure you using only the domian name:
mydomain.com

and not adding in the page name:
page.php

i've followed all the steps in a completely new pg with the same result. Now what? Still no luck.

please post a link where I can see the problem occur.
