Hello, Antonis,
Thank you for your response.
We opened your site after activation VPN.
We’ve updated the theme and XStore Core plugin.
We disabled Wishlist and Compare plugins because now you can find this functionality on Theme Options > WooCommerce.
Also, we enabled XStore Ajaxify in settings of elements on your Home page, for example – https://prnt.sc/RkniFUX5OhTB
Please check descriptions of all plugins that are activated on your site and disable plugins you do not really use because every additional plugin slows down the site a bit.
As mentioned here https://xstore.helpscoutdocs.com/article/100-how-to-speed-up-my-website , the most important part of optimizing your site is caching, so we would recommend you use cache plugin. Contact support of cache plugin to find out guidance about the best settings configuration.
Reduce initial server response time – for this contact your hosting provider.
Kind Regards,
8theme team
