I am receiving this message on one of my sites in my network;
Warning: in_array() expects parameter 2 to be array, null given in /home/****/public_html/wp-includes/post-template.php on line 1039
I have recently updated to wp3.5 and it only appears when clicking on a product catergory. Three lines of the above error, one for each the menu items??? not sure only guesing.
Anyone any clues how to approach this one? Marketpress or Theme?
