Buy now button don't visible some products page

[jaygupta-tech]

Hello I am using the prestige theme and buy the theme a few days before but

When I publish the theme then "Buy now Button" does not show some products page but When I click on the "Add to Cart" button then a error message shows like this - "Required parameter missing or invalid: items"

Here is the product link url - https://nainpreet.com/products/nadia-farooqui-esmir-luxe-velvets-23-aylin-kaftan-rts?variant=4571217...

Please help me, It's too really urgent because the prestige theme already published and these error's are on it.

Hi @jaygupta-tech ,

Seems you put an extra semi-colon and script variable not getting the store id.

Please refer to the below screenshot to understand why this issue is coming.

To resolve this first install a fresh theme, then install your apps one by one.

Hope this could help...
