HTML Scramble (Google Maps)

Whatever I add to the blog, an amazon Banner, or a Facebook Like Plugin, it always turns out as a piece of google maps (see: kruemke.de sidebar and under SOME posts) …
I had a google map html-link in one of the older posts (which is not affected) and deleted it now, but it just seems to stick to the whole blog … how can I get rid of that ?
(I turned all plug-ins on and off already)
