title: "Database Update Required" wordpress caused login issue
body: <p>We updated Wordpress admin panel to 4.0 and following that, was directed to a window that said: </p>
  
  <p>*Database Update Required
  *WordPress has been updated! Before we send you on your way, we have to update your database to the newest version.The update process may take a little while, so please be patient.**</p>
  
  <p>We clicked on "Update database", it took us to a window that said:</p>
  
  <p><em>'Update Complete
  Your WordPress database has been successfully updated!'</em></p>
  
  <p>We clicked continue, and it sent us back to "Database update required" window, we've been going around in a LOOP like this without access to the admin panel...</p>
  
  <p>Then we found the answer to the problem here 
  <a href="https://stackoverflow.com/questions/17308436/wordpress-error-database-update-required">Wordpress Error: Database Update Required</a></p>
  
  <p>So we did that:</p>
  
  <pre><code>Go to /wp-include/ folder and open the version.php.
  Find the value for $wp_db_version, and write it down.
  Now, open your database, check in the table called wp_options
  
  Find the db_version value:
  
  SELECT option_value FROM yourdatabase.wp_options WHERE option_name = 'db_version';
  
  Those two values must be the same. Change it in the version.php file, not the database.
  </code></pre>
  
  <p>We fixed a part of the problem, because now we don't have the 'database update' window showing up anymore, we see the normal login page.</p>
  
  <p>But we can't login! It's impossible. It doesn't react at all, it just refreshes again and again and again...and we never get in the admin panel.</p>
  
  <p>Can someone help us? We're not professional web developers, we're just 2 girls with a webzine trying to resolve this issue. ( so please don't talk to us like we know the A to Z of coding!)</p>
  
  <p>Ps: We have some plugins which we did not disable during the updating process. Also, a few days before this all happened, we downloaded some plugins that didn't work out, but we removed them.</p>
