FTH not displaying correctly after added custom web page

I created a custom web page ("10 tips for powerful online meetings... ) to 2728.toastmastersclubs.org
I added text, links and a photo via the admin panel. Now the site is not loading correctly. I did nothing I thought the least bit unusual.
Attached is a screengrab showing the site loaded in Safari on a Mac.
Please repair whatever I did wrong. And tell me what I did, so I don't do it again.

I had to clear your website banner again, floating text, and main page header.
STOP updating your website banner, you are inserting crap.
Leave it alone.
