Pls check thru replies on this topic, it's not issue of templates. You also tried with default template Protostar and other plugins but it doesn't work, something wrong with your site (like my last post).
You can try to switch to Protostar template + using 1 plugin, then ask the provider of that plugin to see what's wrong. If it works with Protostar template, it will work well with our template.
