WordPress admin-ajax.php 404
<p>Okay, I've been struggling with this for hours now.</p>

<p>When I try to customize my theme, it gives me <code>admin-ajax.php</code> 404 on both POST and GET requests, and does not allow me to make the desired changes :/
The file is definitely there, triple checked via cPanel.</p>

<p>Ran fresh install of WordPress three times now, both the newest 4.4.2 and older down to 4.2.0 because, who knows.</p>

<p>This happens in the default themes and any theme I add. So confused. Help?</p>
