Thank you for a great plugin. I am getting a PHP warning at every site load looking like this:
[24-Jan-2012 15:57:46] PHP Warning: in_array() expects parameter 2 to be array, string given in /wp-content/plugins/advanced-custom-fields/core/fields/checkbox.php on line 58
Do you know a solution to this problem? Am I causing it by some malconfiguration of my fields?
