Warning: Illegal string offset 'message'

[gnikolopoulos]

Hi all,

I am trying to setup this plugin on a website, but while completing the order and I enter the (dummy) credit card details, I get the following error:

Warning: Illegal string offset 'message' in /home/foodioanninagr/public_html/wp-content/plugins/woo-payment-gateway-national-bank-greece/woocommerce-nbg-payment-gateway.php on line 516

Warning: Illegal string offset 'message_type' in /home/foodioanninagr/public_html/wp-content/plugins/woo-payment-gateway-national-bank-greece/woocommerce-nbg-payment-gateway.php on line 517

Warning: Cannot modify header information - headers already sent by (output started at /home/foodioanninagr/public_html/wp-content/plugins/woo-payment-gateway-national-bank-greece/woocommerce-nbg-payment-gateway.php:516) in /home/foodioanninagr/public_html/wp-includes/pluggable.php on line 1179

Any idea what am I missing here???
