array error

If you enable the WP_DEBUG in the wp-config.php file, you’ll find that the plugin actually has this error happening (it just doesn’t display on the live site.)

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /wp-content/plugins/wp-pagenavi/scb/Options.php on line 44

Is there a fix for this?
