Hello,
Thank you for reaching out to us.
– We recommend that you disable all third-party plugins that are not included with XStore (https://www.8theme.com/documentation/xstore/plugins/included-plugins/). After doing so, please clear your browser’s cache and check again. It is possible that one of these additional plugins is causing the issue.
– Could you please test if the same issue occurs when using a default theme, such as Storefront? (go to Appearance > Themes > Install and activate Storefront).
If the behavior continues regardless of the theme being used, it suggests that the problem may not be related to the theme itself. In this case, we would recommend you contact support of woocommerce plugin – https://wordpress.org/support/plugin/woocommerce/
Warm Regards,
The 8Theme Team
