This helped! Thank you guys.
When I cleaned Opera's cache and cookies directly from Opera, nothing changed, but then I did the same thing with Ccleaner and that worked perfectly.

I've never encountered on a rendering (loading) problem like this one, will know in the future what to do.
Thank you once again.

I'm gonna try with Adguard as well

I tried opening opera in private window, and FB renders correctly, but now I'm trying figure out what extension could cause this rendering problem, because I'm using only one extension Adblock v2.41, and none other.

I disabled the Adblock extension, but that didn't help. Still same problem in normal mode window.

Is there any other reason this would render incorrectly, while in private mode everything seems good?

Hello,
I really like using Opera, but recently an annoying problem occurred - the facebook page is loading in a funny way (everything is mixed up - please, see link). I'm using Opera v32.0, and I can't find what is causing this problem.
