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