Getting error message when adding field to Loop Ad Bottom
I tried to mark one of the ad fields to also display in the Loop Ad Bottom and I got the following warning message on the main page ad display:
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /storage/content/69/101769/sporthorses.se/public_html/wp
-content/plugins/advanced-custom-fields-for-ClassiPress/advanced-custom-fields-for-ClassiPress.php on line 876
"Valack |" is the ad field that I like to display so it showed up, but with the Warning before so something is wrong. What can I do?
