Why is my entire store displaying a white blank page after adding booking code?

[Revivify]

Hello,

Please help!

I need help to fix my code please. I was trying to add a booking code to my liquid code and clearly it has not worked and now all I can see is a white blank page. When I "customise" my theme, all the information is still listed on the left however the preview is still white. 

Store URL: https://revivifyivtherapy.com/

Hey Revivify ,

 Are you using a debutify theme? 

I have found the issue , a div is overlapping on all over the page. you can add the below css in your theme.scss.css file. 

.dbtfy-page_transition{  

  display: block;

  visibility: visible;

  opacity: 1;

  position: inherit;

  height: auto;

}
