title: Responsive file manager plugin image upload fails due to insufficient memory
body: <p>When I am trying to upload an image via Responsive Filemanager 9.11.3, I get "not enough memory" error. It returns HTTP 406 error code.</p>
  
  <p>After looking out the solutions on the internet, I could verify following parameters are already set accordingly.</p>
  
  <p><strong>php.ini</strong></p>
  
  <blockquote>
    <p>post_max_size = 100M</p>
    
    <p>upload_max_filesize = 100M</p>
    
    <p>memory_limit = 2G</p>
  </blockquote>
  
  <p><strong>config.php (Responsive filemanager)</strong></p>
  
  <blockquote>
    <p>'MaxSizeUpload' => 100,</p>
  </blockquote>
  
  <p>However, I could not upload even a 232KB image. How can I resolve the issue?</p>
