Safari & Chrome not displaying page right

Jordan, start with validating your site. It has several coding errors and the theme also seems to have a (css) problem. With these errors the site will never display properly in all browsers. After getting rid of the errors you can concentrate on left-over problems.

if you haven’t made any changes to the theme, contact the theme author for support.

I tried that, but thanks.

sometimes, plugins interfere with the theme.
try and deactivate all plugins to see if the effect is still there, and if that resolved the display issues, then reactivate one plugin at the time, to see which is not compatible with the theme.
