9.1. I can’t add more than twenty fields
If you're experiencing this issue you can try one of these options to solve it.
Usually, this is due to a limit on the number of POST fields that can be sent to the hosting server in a single submission. For some hosts, this limit is 1000. As a consequence, this limits the number of Checkout fields you can add via the WooCheckout screen.
To add more than 20 checkout fields for a given Section (e.g. Billing, Shipping, Additional) you will need to increase the ‘max_input_vars’ PHP option. You can do this globally in all your WordPress sites or on a per-site basis. Apply this change globally by editing your hosting server’s php.ini file as follows.
max_input_vars = 2000
Alternatively, you can apply this on a per-site basis by adding the following code to your WordPress site’s .htaccess file.
php_value max_input_vars 2000
