Hi Bhaskar,
When using the product_category shortcode in the end result the title is not Clickable of the product.
By default, this shortcode renders a list of products where all its elements (image, title, price,…) are clickable and forward the customer to the product page.
If this isn’t happening in your case, I suspect that your theme or some of your active plugins can be affecting the default behavior of this shortcode.
The best way to find the origin of the issue is to switch to a default theme like Storefront and disable all the active plugins except WooCommerce to see if the issue is fixed. If that’s the case, you just need to reactivate the disabled plugins one by one and reload the Checkout page to check if the issue reappears. You’ll know the culprit plugin when you reactivate one and the problem reappears.
Of course, I’d suggest you to perform this test on a staging version of your site (you can use “WP Staging” plugin to create one quickly).
