WPPA relies on the wp function is_ssl() and other wp functions that provide standard urls like admin_url(), includes_url(), site_url() and plugins_url(). In your case these functions all erroneously return http://. See this code snippet of your pages source:
<script type="text/javascript">
wppaImageDirectory = "http://rmb.barronsplace.com/wp-content/plugins/wp-photo-album-plus/img/";
wppaWppaUrl = "http://rmb.barronsplace.com/wp-content/plugins/wp-photo-album-plus";
wppaIncludeUrl = "http://rmb.barronsplace.com/wp-includes";
wppaAjaxUrl = "http://rmb.barronsplace.com/wp-content/plugins/wp-photo-album-plus/wppa-ajax-front.php";
wppaUploadUrl = "http://rmb.barronsplace.com/wp-content/uploads/sites/8/wppa";
wppaIsIe = false;
wppaIsSafari = false;
wppaUseSvg = true;
wppaSlideshowNavigationType = "icons";
wppaAudioHeight = 40;
</script>
wppaImageDirectory, wppaWppaUrl and wppaAjaxUrl are – indirectly – based on is_ssl()
wppaIncludeUrl is based on includes_url()
wppaUploadUrl is based on site_url()
I suggest you address this isuue to the wp core developers. This is not a wppa issue.
Jacob,
Adding the following code to wp-config.php did the trick, thank you for your great plugin and fabulous support ….. Rick
