When I tested the search widget, I received the following error:
Warning: Illegal offset type in isset or empty in /home/…/wp-includes/post.php on line 1038.
search string is: ?s=keyword&post_type=product
I use Woocommerce together with a premiumpress theme. In another thread here on wordpress forums there was a user who said the following:
“Basically, you have a plugin registering a post type incorrectly, and then core complains. It isn’t a bug in core best I can tell.”
Anyone any idea how to solve this?
