Validation error messages are not showing in product page

Hi @markhf,

I have added a plugin for extra product options

https://www.themehigh.com/product/woocommerce-extra-product-options

Validation error messages are not showing in the product page while clicking the subscribe button. I have contacted the support team, they told me that,

“On checking, we could see that in the theme there is a feature of adding the product to the cart without reloading the page. They are not picking all the data in the form field of the product page. This is the reason why the validation is not working for the normal product. So we recommend you to contact your theme developer or theme support.

Regarding the subscription plugin, they are clearing the validation message. It is added while clicking the subscription form. This validation message clear occurs while un-ticking the “Allow Mixed checkout” option of the subscription. In-order to debug further on this issue, we recommend you to contact the plugin support.”

This is my product page

Could you please help me on this

Thanks in Advance
