Text Alignment outside the Required Space

Hi,

I’m having difficulty with the text alignment only when I click the Archive link. The text goes partially outside the column area and overlaps the side column which makes it hard to read.

The same problem repeats when I click the category link or when I view a search result… Fortunately, the home page and the posts has no such problem at all.

Here are samples of the problem (please note that the text is in Arabic Language):

I checked the style.css file many times trying to find out where is the error but I couldn’t.

Appreciating your support in advance..
