Hello, @Alzain,
Thank you for your response.
1/ We recommend reaching out to your website developer to address the child theme additional code customization issue. Alternatively, you may consider installing and activate a new child theme on your website, which could potentially resolve the problem.
You can download the new child theme from the following link: (https://www.8theme.com/downloads/)
Please note that additional code customization falls outside the scope of our basic support services.
2/ We kindly request that you add a new archive template to your website. For guidance on how to proceed, please refer to the steps outlined in our theme documentation, which can be accessed via the following link: (https://www.8theme.com/documentation/xstore/xstore-builders/xstore-products-archive-builder-with-elementor/).
We trust this will assist you in updating your site effectively. Should you require any further assistance, please do not hesitate to reach out. We are here to help you.
Best regards,
The 8Theme Team
