Problem with menus

[simo80]

Hello everyone.
I have written long ago for the exact same problem, I can not completely resolve.
Sorry for the bad English but use a translator.
I will try to explain the problem using many images.
Firstly this is my site:
http://www.dimmicosacerchi.it/

Every time you add a widgets, the site becomes very messy, moving the menu on the left side of the page (see photo)




Today the site was in place.
I posted two articles and two widgets.
And I have activated the plugin "All in Seo.
Half an hour later, the site was.

Despite netting has removed the two widgets placed today, and disabled the plugin, the site is not coming back.


A few weeks ago, I had the same problem.
I removed all the widgets, and reinsert the problem was solved.
But this time no. Help me please. :(
