Whenever someone uses my contact form, the information is sent fine to my email, however; an error message pops up above the contact form.
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /plugins/contact-form-7/wp-contact-form-7.php on line 971
I looked at the line 971 and it says:
$multiple && in_array($value, $_POST[$name]) ||
Any idea on how to resolve this issue? It's working fine otherwise.
I did notice that the confirmation messages aren't outlined in green or red.
