Hi Tamer,
I am sorry for the delay of this reply due to the different timezone here in our end.
I've checked your cron command and it seems like you are using cron.php command instead of cron=true. If you are using cron.php you need to manually edit the file /components/com_easysocial/cron.php at line 19 for every easysocial update on your site:
$host = 'site.com';
// replace site.com with your site domain name as example below
$host = ''stackideas.com';
I've helped you to edit the file and the cron should get processed correctly now.
