HTTPS problem and simple fix

The plugin doesn’t call the plugin directory in a way which preserves “https” for secured sites.

A simple fix is to edit advanced-post-slider.php

And replace this:
define(‘advps_url’,WP_PLUGIN_URL.”/advanced-post-slider/”);

With this:
$awk_content_url = content_url();
define(‘advps_url’,$awk_content_url.”/plugins/advanced-post-slider/”);
