[Plugin: Ajaxy Live Search] Warning in exclude

Hi,

I get this warning:
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /plugins/ajaxy-search-form/settings/sf_edit-form-advanced.php on line 185
name=”sf_exclude_post[]” value=”26165″/>
It shows only 5 posts to exclude.
Can anyone help me with this?
Thanks!
