Fatal error: Mercado Pago compatibility

Hi Karolina,
First of all, thank you for this great plugin.

I just noticed the following error on my site when trying to get to the settings section of any payment method.

Uncaught TypeError: array_merge(): Argument #1 must be of type array, null given in /www/htdocs/wp-content/plugins/woocommerce-pay-for-payment/inc/class-pay4pay-admin.php:233
Stack trace:
#0 /www/htdocs/wp-content/plugins/woocommerce-pay-for-payment/inc/class-pay4pay-admin.php(233): array_merge(NULL, Array)
#1 /www/htdocs/wp-includes/class-wp-hook.php(303): Pay4Pay_Admin->add_payment_options('')
#2 /www/htdocs/wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters(0, Array)
#3 /www/htdocs/wp-includes/plugin.php(470): WP_Hook->do_action(Array)
#4 /www/htdocs/wp-settings.php(600): do_action('wp_loaded')
#5 /www/htdocs/wp-config.php(96): require_once('/www/...')
#6 /www/htdocs/wp-load.php(50): require_once('/www/...')
#7 /www/htdocs/wp-admin/admin.php(34): require_once('/www/...')
#8 {main}

It was working ok a few weeks ago. I believe it might be related to the last update on Mercado Pago payments for WooCommerce plugin. If I deactivate that plugin it works ok again, but the fee should be applied to Mercado Pago.

I checked the forum and the same problem was solved last year with the following line (233):
$gateway->form_fields = array_merge($gateway->form_fields, $form_fields); // Fix Mercadopago integration
But it is not working anymore.

It is possible something changed by then? Any suggestions on how to fix it?

Kind regards,
