Сайт перестал работать. Пришлось откатывать. Специально зарегистрировался, чтобы
влепить кол.

It’s not for the faint of heart, but if you want your Google page speed to hit 100
and you don’t want any FOUC, you need this plugin. Needs a little work to support
our Custom Post Types, but it still gets a 5 because it’s awesome. Donation forthcoming
as soon as my boss gets on it..
