Right position

Hi.
Suddenly the right position went at the bottom of the homepage (only there in all the other pages works fine). I disabled the modules one by one but without success.
Any thoughts.

I am sorry to say but it does the same problem in 2-3 other menus.

you have un-closed div tags in content that suck in right column

Please could you be more specific?
I have to notice that I didn't have any problem with the same modules in right position for some days.
And I only add k2 items.
Now. I disabled everything in right position except a single photo. As you could see in 1st, 7th and 8th menu it keeps space for the right position but the content (this photo) is at the end of the page. In every other menu works fine !!!
(I tried the same using other modules. For example just a word in a custom html. It does the same)

Well no i would take like haf of hour for me to locate that so it's task for you I'am sure that is problem because right column fall into well known other container, and that is 100% sign of that problem

And why this is happening in some menus and not all of them?
Shouldn't have the same reaction?
