I maybe found workaround, try to logg off facebook, then logg back in and see if it works, but that is very dissapoiting from Opera...

it loads only header of the facebook page, without anything else, sometimes it loads only few news on facebook, without contacts or friends. Also, sometimes there are issues with opening www.google.hr on some PC-s that I use. they all have clean install of windows 7.

Yes, I know that 12.17 is old version, but is very reliable and faster than most browsers,I have Firefox and Chrome also on my PC, but Opera is my main browser and I don't like to use other browsers and Opera 22 based on Chrome and I don't like it- Also, some things that are in old Opera aren't implemented in Opera 22 and if Opera don't implement all features from old Opera, I will be forced to switch on Firefox and that is getting on my nerves....

Does anybody know what is happening with Opera 12.17 and Facebook? I use it on 10 PC with different specs and Windows and on all computers is same issue. Opera cannot open correctly Facebook page.
Other pages that I visit are working fine.
Those problems started 2 weeks ago and still are here.
Any ideas? Opera staff?

EDIT: Firefox, IE and Chrome are working normally, extensions are all off.
