<h3>Troubleshooting</h3>
The Ad Widget is a very simple plugin. If you are having trouble 
loading ads on your site, please make sure that:
<ul>
<li>You do not have an ad blocker installed (you would be amazed how often this happens). Disable it and refresh the page a few times to see if the ad appears.</li>
<li>You don’t have CSS in your theme which is hiding images (rare, but it happens)</li>
</ul>
If you have any other trouble, email kenny@broadstreetads.com – try to avoid 
the WordPress support forums because they’re awful.
