Hello @bhabani,
Have you created your single product page using the Elementor Pro plugin? If so, please reach out to the Elementor Pro plugin support team regarding this issue.
It appears that this is a third-party plugin conflict on your site. We suggest disabling all third-party plugins (including cache plugins) that are not bundled with XStore (https://xstore.helpscoutdocs.com/article/36-included-plugins), clearing the browser cache, and then checking again. It is possible that one of the additional plugins is causing the problem.
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.
Also, please provide your site’s WP Admin URL and credentials in the private content area of this topic, so that we can investigate further.
Regards,
8Themes Team
