title: Sections must only appear once per config file
body: <p>so yesterday this code was working just fine and today as we went to run the site we are getting this configuration error. I have looked through the other questions asked and although they were helpful I have not been able to pinpoint where I am repeating a section.</p>
  
  <p>Here is my error:

  <p>Thank you all in advance for the help, I'm sure it's something small I'm missing. Been staring at the code for too long maybe. </p>
