title: TYPO3 - upload_max_filesize installation error
body: <p>I get the following error during installation:</p>
  
  <blockquote>
    <p>PHP Maximum upload filesize too small PHP upload_max_filesize = 11 MB
    TYPO3_CONF_VARS[BE][maxFileSize] = 10 MB</p>
    
    <p>Currently PHP determines the limits for uploaded file's sizes and not
    TYPO3.  It is recommended that the value of upload_max_filesize is at
    least equal to  the value of TYPO3_CONF_VARS[BE][maxFileSize].</p>
  </blockquote>
  
  <p>I've changed the php.ini setting to 11MB, also <code>post_max_size=12</code>. How do I fix this error? Should I modify <code>TYPO3_CONF_VARS[BE][maxFileSize]</code> and set it to some lower value?</p>
  
  <p>Thanks!</p>
