For some reason my layout is not 2 columns in IE

First thing I get is a massive Error in IE…

Meldung: Undefined Runtime-Error
Row: 3
Zeichen: 4589
Code: 0
URI: https://www.cancerfonden.se/Contribution/Elements/CollectionWidget/WidgetStripe.aspx

Maybe if you fix that, it will be ok. My IE crashed right after that so I can’t see much more for now.

Ah … and first the page is fine. Only after all things have loaded, it turns into one column.
