Hello @Srinivasan,
Are you using a Child Theme on your site? Have you added any Customization code to the Child Theme? If so, please comment it out and check back.
Alternatively, please try disabling all 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 again. It is possible that one of the additional plugins is causing the issue.
If the issue persists, please keep all third-party plugins deactivated on your site and grant permission to debug your site, which includes deactivating all third-party plugins and on-site Customization.
Please note that you should take a complete backup of your site before doing so.
Please also provide your site’s WP Admin URL and Credentials in the private content area of this topic, so that we can investigate further.
Best Regards,
8Theme’s Team
