Hello romagromov,

Sorry for late reply to this,
Can you try this following cron command and see how it goes?
/usr/bin/wget -O /dev/null "http://vsehristiane.com/index.php?option=com_easysocial&cron=true >/dev/null 2>&1

If the result still can't, can you provide us with your Joomla backend and Cpanel access so we can help you check on this?
By the way, can you consult with your Webhosting provider what is your site wget path as well.
