Sometimes when you create a product with multiple attributes in Magento 2, you may end up with the error message “Invalid Form Key. Please refresh the page.

Magento 2 invalid form key please refresh the page
Magento 2 “Invalid Form Key” error

To get rid of this message, you need to increase the value of max_input_vars in php.ini file. By default, this value is set to 1000. You should set it to 5000 or 10000. To do that, follow these steps:

1. Log in to your website server using ssh
magento server login

2. Go to the folder containing php.ini and open this file by vi

3. Edit the value of max_input_vars to 5000 (or create it if it doesn’t exist yet). Then, press ESC key and type :wq to save the file.

4. Restart your Mamp or Apache. Now you can save your newly created product without any problem.
