Are there any emails generated in the mail activities on the site? Notification mails are stored under the "Email Activities" area. Check if those mails are marked as sent. If they are already marked as sent, EasyDiscuss has already sent them through Joomla's mailer API. If the mail still doesn't reach the user's end, you will need to check your mail settings under the Global Configuration.

Configuration is correct. I send email via php scripts on my site use Joomla's mailer API. All messages in "Email Activities" area not marked as sent.

Hi,

Can you provide us with your Joomla backend and FTP access so we can check on the issue directly? May I know have you configured the cronjob for your easydiscuss? Please advise.

wget http://proved-expert.ru/index.php?option=com_easydiscuss&task=cron
doesnot work.

Hi,

Can you provide us with the following credentials so we can check on the issue directly?
1) Joomla backend access
2) FTP access
3) Your cronjob setting access

If you are unable to provide the credentials for some reason, can you change the cron command with the following instead and see how it goes?

/usr/bin/wget -O /dev/null "http://proved-expert.ru/index.php?option=com_easydiscuss&task=cron"
