As discussed with divi theme and they said if we need to work and return products after woo product search then we need to remove shop page from woocommerce->settings->products->shop page.
Right now we designed shop page with divi builder and showing products on shop page using divi shop module.
I tested this also when i removed the shop page from settings then woocommerce search function is working and shows products instead of blank page. but in that case our designed shop page is not working and it shows default woo shop page.
We can’t remove the shop page and we can’t disable the divi builder.
From divi support they said: We’re sorry but this is not a theme limitation, it’s a WooCommerce limitation
Please suggest us some solution for this.
