title: Importing SQL file "Duplicate entry '0' for key 'PRIMARY'"
body: <p>I know there is similar questions that are answered but please try to help me out.</p>
  
  <p>I'm importing a backup of my MyBB database into a new host using PHPMyAdmin. When trying to import the .sql file, I get the following error:</p>
  
  <p>SQL query:</p>
  
  <pre><code>INSERT INTO mybb_datacache(  `title` ,  `cache` ) 
  VALUES (
  
  'internal_settings',  'a:1:{s:14:\"encryption_key\";s:32:\"rrvohvVATtOauucNTmEXAmvNvbw9ujvb\";}'
  );
  
  MySQL said: 
  
  #1062 - Duplicate entry 'internal_settings' for key 'PRIMARY'
  </code></pre>
  
  <p>I can't figure out the problem. I emptied all tables and clean install of the database four times already. I've been trying to figure this out all day and it's very frustrating.</p>
