When used "more" wrap & background colour changes

Hello,

on the site kabeltec.si I used categorie list of articles (blog). It looks ok untill I used "read more" in certain articles. First I noticed that the background colour of main_area changed to the same as bottom_wrap, and later that the whole list of articles and other modules are actually displayed in bottom_wrap and that's why the colour has changed.
You can check the difference when used "read more" here:
www.kabeltec.si/prodajni-program/vde-odobreni-kabli (without "read more")
www.kabeltec.si/prodajni-program/fotovoltaika (with "read more").

This is not supposed to happen...

Best regards

I think it's case of broken HTML. Article content cut before closing of DIV tag. You can just remove all div-s from your articles content and configure editor not to use then if it uses them currently

O.k. - that was the problem.
