My XStore theme website http://www.cazok.com is too slow. The dashboard is working fine. But front-end took about 50Sec to load!! Sometimes the connection can not be made also. When I tried other themes, Its works fine. I’m using latest version of XStore and WC.
I’m only using minimum plugins required. The website is running on A2 Hosting (WordPress recommended hosting provider).
We have checked your site and see that you use PHP version 7.2.2, Visual Composer does not fully support this version and it could be the reason of your problem. Can you, please, downgrade PHP version to 7.1, please, and let me know about results.
