title: another Wordpress contact form 7 file upload issue
body: <p>I know this problem is often related, but i'm struggling with the informations i get. I want to make an upload file field which handle files up to 10mo.</p>
  
  <p>here is a sample of my phpinfo :</p>
  
  <pre><code>max_input_time : 300
  max_execution_time : 300
  upload_max_filesize : 300000M
  post_max_size : 300000M
  memory_limit : 512M
  </code></pre>
  
  <p>I also added this line to wp-config.php</p>
  
  <pre><code>define('WP_MEMORY_LIMIT', '64M');
  </code></pre>
  
  <p>to finish, here's the notation of my file input in contact form 7 :</p>
  
  <pre><code>[file file limit:20mb filetypes:txt|pdf|doc|docx|odt class:fileinput]
  </code></pre>
  
  <p>with these settings, i can upload files up to 8mo, but i need 10mo. Can't see what's wrong at this point</p>
