I’ve ruled it out. Indeed, when I selected the fonts with Cyrillic support it worked. Pity that original fonts doesn’t have it because I really like how you combined them.
Just enabled it and still no luck. Could it be the fonts selected for the content don’t have a Russian representation and they must me changed in themes customisation?
Thank you for this timely update. Unfortunately I am unable to see the difference. I’ve installed the 3.5 version, activated it and nothing changed. No cashing is enabled in my blog and I’ve tried 2 computers and 3 different browsers.
