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.”
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
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.

You need to change your action=”mageplaza_helloworld/post” It goes like this : action=”{router_name} / {controller_folder} / {action_name}” Your router name is your namespace and module name – in this case it is Mageplaza_HelloWorld Your controller folder is the folder inside app/code/Mageplaza/HelloWorld/Controller/Adminhtml – in your case it may be Post Your action name is the .php file inside app/code/Mageplaza/HelloWorld/Controller/Adminhtml/Post – in your case it may be Index.php TLDR: In your app/code/Mageplaza/HelloWorld/etc/adminhtml/menu.xml On the line that… Read more »

I have Magento 2.4.1, max_input_vars is 20000 but still having the invalid key issue for only one product attribute(Dropdown with 13 options), when I save it without change, or update its values. I can edit this particular attribute only…
