It's a bug... to fix do the following:
In search_function.php find:
PHP Code:
else {
$num_in_strings_arr = count($strings);
$leven_final = "";
$leven_sum = 0;
And replace with:
PHP Code:
else {
if (is_array($strings)) {
$strings = array_values($strings);
$num_in_strings_arr = count($strings);
}
else { $num_in_strings_arr = 0; }
$leven_final = "";
$leven_sum = 0;
