Make sure that you are using the latest version of the theme – https://xstore.helpscoutdocs.com/article/63-theme-update , then read our docs – https://xstore.helpscoutdocs.com/category/131-xstore-features
If this doesn’t help, try to disable ALL the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear the cache of the browser, and check then. Maybe one of the additional plugins is the reason for the problem.
