Despite its prevalence, this is not a specific Magento bug. It is one of the most commonly encountered Magento issues. The following are some of the Magento 2 shop actions that produce this error:

• During the making of a configurable product with multiple attributes.

• When installing a new extension/ theme on Magento 2.
• After upgrading Magento 2 version.

The reasons for Magento 2 “Invalid Form Key. Please refresh the page” error

Listed below are two of the most common or popular reasons for the error to get triggered.

1. PHP Max_input_vars value is not optimized for Magento 2

The date error is caused by an incorrectly specified Max input vars value in Magento 2. The server’s default PHP MAx input vars value is 1000, which is insufficient for Magento 2.

PHP Max input vars is the maximum amount of variables that the server can use for a single function in order to avoid overloading (this value is used mainly to protect the server from DDOS attacks).

2. Base URL on Localhost not recognized by Magento 2 system

If this problem occurs on Localhost, it is most likely due to utilizing Localhost as the website’s base URL rather than 127.0.0.1.

This will almost certainly result in a cookie system issue on Magento and a Magento 2 Invalid Form Key. If this is the case, please reload the website page.

sudo rm -rf var/cache var/generation var/page_cache
