Layout verschoben, nur im IE..und nur auf Artikelseiten

Hallo

Ich hab heute mal mein Portfolio umgemodelt.
http://www.herr-loeffler.de
Is ja auch alles in Ordnung, nur im Blog auf jeder Artikelseite ist das Layout viel zu weit nach Links gerutscht. Allerdings nur im IE

Ich find aber den Fehler nicht...

Hier mal das CSS.. vielleicht sieht einer den Fehler
