I didn't use custom file, everything by default.
After installation all is well.When I visit Webserver config page, change owner, create domain error eppears and php error log says:
"[03-Jul-2016 18:28:22 Europe/London] PHP Warning: PHP Startup: xmlrpc: Unable to initialize module

These options need to match

I restart php-fpm and all runs well.
So, there is nothing i can do.
