title: Nav bar disappear when I open specific page for second time
body: <p>I have an issue with my nav bar. </p>
  
  <p><strong>Issue:</strong> </p>
  
  <p>For example I have two pages. A homepage having sign in button and a sign in page. I have a back button on sign in page to go back to homepage. First time I press the back button, it works. But when I press sign in button again from the homepage, sign in page opens but without nav bar.
  <br/>Here is the code of my sign in page, using desktop Ionic and running the project using Ionic serve in cmd. </p>
  
  <p>Ask any further info you need.</p>
  
  <p>Thanks in advance :)</p>
