Apache extensions for WordPress’ working without troubles

So, I need to say that now is all ok. I can’t belive this :’) For about a month I asked a lot of people and nobody didn’t know what’s the problem.
It was cause we had bad nginx config. Now nginx is turned off for a some time. Apache is ok.
Thank to s_ha_dum, thanks to Rarst
