Ok, I did what you suggested and it worked – as soon as I deactivated the plugins and changed the theme, everything looked normal again. Then I reactivated the plugins, switched to the previous theme and… same thing as before!
I assume it’s a problem with the theme? But it was working well before so I don’t understand what happened… Anyway now I put another theme (which is not twentyten) and it works.
My blog is at blog.travelreportage.com and the theme I was trying to use was AutoFocus+ (the one I put now is AutoFocus 1.0.1)
Is there anything I can do to go back to Autofocus+ or I just have to forget about it?
Thanks!

p.s. all plugins work, anyway I deleted the obsolete ones. I have just 4 now (Akismet, WP Stats, WP Facebook Like and AddToAny.
