I just got a message from someone in Germany who told me he had been promoting my site, but the site wouldn't show.
On my end, it shows up like it should, in IE, Firefox and Chrome.

Here's what he sees:



and here's what I see:



It's a site built in WP, using the Rapidbuilder theme

I simply have no idea where to start looking for a solution, since I have no idea at all what could be causing this...

Does anyone have any ideas?
Is there a way to check how sites show up in other parts of the world, maybe?
