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.

Hi,
Thanks for the help.
I tried you method but it didn’t solve the issue for me
Actually i’m newbie in magento 2 development.
I’ve been working on magento 2 module.
So i created a admin menu and everything works good.
But when i click on the created menu, it goes and redirects admin dashboard page and display the error
Fyi, i doing this in windows 7 PC and localhost server xampp
Any help would be appreciable.
Thanks,
Hussain.
Hey, I had the same problem, your admin menu action attribute is wrong.
So for example, in your
app/code/Mageplaza/HelloWorld/etc/adminhtml/menu.xml
There is line where you specify your route.
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 gives you error after clicking:
Change
action=”mageplaza_helloworld/post”
To
action=”mageplaza_helloworld/post/index”
I hope you understand me 🙂
