[Bugfix] HTTPS Mixed Content issue because of your plugin.

plesae have a look in the file:

includes/libuary.php Line 75:
actual code is:
$like_box_src=add_query_arg($like_box_array_query,'https://www.facebook.com/v2.6/plugins/page.php');

On SSL Pages there is afterwards a mixxed content issue. Therefor on ssl pages it need to be loaded from HTTPS. To fix it, that it works for non SSL and SSL pages, pleaes change it to:

$like_box_src=add_query_arg($like_box_array_query,'//www.facebook.com/v2.6/plugins/page.php');

Bug is then fixed.

Thanks and regards
