Error message received on Easy Blog recent posts module

Here's the message showing in the recent blog module, just above the one blog listing shown:

Warning: in_array() expects parameter 2 to be array, string given in /home/mhlas487/public_html/administrator/components/com_acesef/library/utility.php on line 369

We've tried several different settings in the module with now success.

Please help.

Thank you.
