The cronjobs are dependent on your hosting company and not the product. Please provide a screen shot of the created cronjob on your end.

I am applying the following crone - */5 * * * * wget -O /dev/null "http://akruga.ru/index.php?option=com_easysocial&cron=true"; &> /tmp/cron.log

I am sorry but unfortunately your EasySocial subscriptions has already expired and we are unable to provide you with support for EasySocial unless you renew your support subscriptions.

could you advise if this is correct string for the cron

*/5 * * * * wget -O /dev/null "http://akruga.ru/index.php?option=com_easysocial&cron=true"; &> /tmp/cron.log

as previously it worked just fine, now it does not

As if i am running it in browser it doe snto work, it is related both to blog and community.

Sorry, but support will only be provided to users with a valid subscription.
