I have my site hosted with Pagely.
They have their own caching plugin
But it turns out that the site theme is causing problems with it.
It’s not caching due to the cookies generated by the site.
As you can see, there are several cookies generated just on the home page. Any plugin or theme that creates a PHP session/cookie will break caching with either present. What that means is that potentially, a single page could have different content for each visitor and it would be dangerous to generate a page once and then serve it from cache to two different visitors. Thus, every single page request would not be cached and consume resources.
However, having your site hit our cache layer is important since that is the first thing you’d want to make sure when optimizing your site for scalability.
They say the site can’t take the advantage of their caching system due to these cookies.
I know there arnother plugin cookies, but I Wanna start with the theme
1) Theme files that you sent in the first message are related to FaceBook login option. If you don’t use it you should not have problems.
2) Please, solve all the moments related to the plugins that you use. After that contact us again if you still have problems because of those files of out theme.
3) wp_woocommerce_session_ – session created by WooCommerce plugin, WC plugin use it because when users add the products to cart they should have them in cart even when they navigate to another page. Other cache plugins, for example, W3 Total cache adds _wc_session_ to the list of Ignored Query Strings.
