Magento 2 : Invalid Key. Please Refresh The Page as we create / login to account

I have installed LAMP (Stack) to my Ubuntu laptop and successfully installed Magento 2.x

So the problem occurred when I need to log in with the customer account at the front-site

I have error message “Magento 2 : Invalid Key. Please Refresh The Page”

so here is the solution I’ve done before

  1. Edit my php.ini files and increase php_value_max_input_vars to 75000 or higher.
  2. Restart my apache server
  3. Clear browse cache
  4. Try to login/create account again
