If just the index.php loads as its generic unparsed self, what exactly is [not] happening?
<p>I visited a client's site today, and I'm getting the actual content of their index.php file itself rather than their website. The function of the index.php file says:</p>

<pre><code>This file loads and executes the parser. *
</code></pre>

<p>Assuming this is not happening, what would be some common reasons for that?</p>
