1. Better use your server as ns until all running well
2. Sometimes, drivers (like webserver) have a problem. Use a trick where go to 'admin > switch program' and choose 'none' for all and then (after click 'update') change to nginxproxy, none, nsd and bogofilter
3. The same way for 'php type', go to 'admin > webserver configure' and then select 'suphp_event' and changr back to 'php-fpm_event'
