SQL Query returns no results (but it's there!)

it's strangely!
Your code works fine for me!

Code:

echo $this->db->query("SELECT * FROM listings WHERE  from_email = '[email protected]'")->num_rows();
echo $this->db->last_query();

2 SELECT * FROM listings WHERE from_email = '[email protected]'

I have two rows in database where from_email = '[email protected]'
