New classifieds update

I updated the plugin classifieds.. Now i am getting this error when you create a new add..

Warning: array_intersect_key() [function.array-intersect-key]: Argument #2 is not an array in /home/womyclas/public_html/ on line 18

Warning: array_reverse() expects parameter 1 to be array, null given in /home/womyclas/public_html/ on line 18

Please could someone assist in this issue?
