I have a form sending a payment to PayPal, which works and gives me an error when I return from PayPal back to the page. Here's the error:
Warning: explode() expects parameter 2 to be string, array given in /home/todd/public_html/members/heights/wp-content/plugins/gravityforms/common.php on line 1504
Is this something I should worry about? If not, can I suppress that error from showing to end users?
