Buy Button Disabled After Variant Change on Customized PDP – Prestige 10.6.0 Theme

Online Store and Theme Development
,
1

Hi everyone,

I’ve built my store using the Prestige 10.6.0 theme and have heavily customized the Product Detail Page (PDP) to match my requirements.

However, I’m currently facing an issue where the Buy/Add to Cart button gets disabled whenever I change the product variant. I’ve tried several approaches to resolve this, but unfortunately, I’m stuck and unable to find a fix.

Has anyone experienced a similar issue or can guide me on how to ensure the Buy button stays enabled when switching between variants?

Any help from the community would be greatly appreciated!

Thanks in advance.

Hey Yash, are there any errors in your console when you change the variant?
