Cart 404 Issue

[gkarthick87]

Hi,

When i'm trying to add product through "Add to cart" button it's showing 404 error. I have migrated this site from 1.9 to Magento 2.3.3. How can I solve this issue?

Please let me know.

It can be form key issue or .htaccess but not sure, please check your logs and share if there any error.
