  <p><strong>Why do I get this error? And how can I fix it?</strong></p>
  
  <p>I have looked around and other people seemed to get this error when they renamed their application, however I haven't done this.</p>
  
  <p>I have created a custom style, if that might have anything to do with it.</p>
  
  <p>I have done no coding, all I have done is dragging on my style's controls and linked the pages.</p>
