Hello @gifts,
We regret to inform you that you have not followed our recommendations.
We do not give a guarantee for full theme compatibility with all existing 3rd party plugins. Sometimes, not always, you need additionally customize the theme or plugin to make them work together. Unfortunately, it’s not possible for the author to make the theme compatible with all the existing plugins and additional customization is outside the scope of our basic support.
As the issue is caused by the WooCommerce TM Extra Product Options plugin, we suggest that you contact the support team of the plugin for further assistance.
We thank you for your understanding and wish you the best.
Kind Regards,
8theme team
