title: Shortcodes show up as text on page
body: <p>For some reason, some of the shortcodes of some of my plugins show up as text on my pages. Could somebody please provide me with possible reasons why this is happening. The main plugins which are causing problems are:</p>
  
  <p><a href="https://wordpress.org/plugins/users-ultra/" rel="nofollow">https://wordpress.org/plugins/users-ultra/</a></p>
  
  <p>wordpress.org/support/plugin/front-end-pm</p>
  
  <p>I have also used the plugins individually, deactivated all of my other plugins one by one and they still show up as text. Any help would be greatly apreciated.</p>
  
  <p>Thanks</p>
