Hi Alec,
I tried logging in and the front end and backend are now showing the same.
May I know how exactly did you change the font of the text “Come Travel with us!”
I can see you have used text element, so the font is the same as your body text. I suggest you use the Headline element instead of text element.
You can then change the font in Theme Options > Typography
or if using Font Manager
Another Option is to enable advanced mode.
You can then set the font on the element itself.
Hope this helps
