title: #1366 - Incorrect integer value: 'NULL' for column 'cid' at row 1
body: <p>I have installed MyBB local using XAMPP and it goes smoothly. But when I do it on the server it give me errors.</p>
  
  <p>MyBB creates and inserts a lot of data by itself and I found out the errors are in queries like:</p>
  
  <pre><code>INSERT INTO... VALUES ('NULL', ...)
  </code></pre>
  
  <p>On my localhost MySQL (which is 5.5.27 for both) accepts this kind of query, where 'NULL' is passed as a String. But in the server it gives an error #1366 as the title says.</p>
  
  <p>The problem is that changing the query is not an option since it is A LOT of queries, so anyone has an idea where I can configure this to work?</p>
  
  <p>Thanks in advance.</p>
