Hi There,
My client unfortunately decided to take shortcuts to avoid extra costs and used someone to edit his site. This resulted in the site going into a fatal error.
Not sure how but they got hold of their host and it was sorted out, but now their paypal no longer works.
When you click checkout this error is shown: Fatal error: Unsupported operand types in /data/www/vagcafe.com/www/concrete/libraries/3rdparty/Zend/Validate/Hostname.php on line 571
I'm not good at error's can anyone inform me what this error means and how to fix it?

Thanks so much!
