Hello Kai,
Sorry for late reply to this,
I have checked in your server response when i added in my email address
/bin/wget -O /dev/null "https://xxx/index.php?option=com_easydiscuss&task=cron"
Then i get this
/usr/local/cpanel/bin/jailshell: /bin/wget: No such file or directory
After that i try put this wget path
/usr/bin/wget -O /dev/null "https://xxx/index.php?option=com_easydiscuss&task=cron"
Then i get this
--2014-06-11 17:35:01-- https://xxx/index.php?option=com_easydiscuss&task=cron
Resolving xxx... 217.23.10.162
Connecting to xxx|217.23.10.162|:443... connected.
ERROR: cannot verify xbit.asia’s certificate, issued by “/C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=COMODO RSA Domain Validation Secure Server CA”:
Self-signed certificate encountered.
To connect to xxx insecurely, use ‘--no-check-certificate’.
But I have tested the email notification, it seems like working now, I have help you set back the time interval 5 minute per process cronjob.
Also, can you consult with your Webhosting provider regarding this why getting "ERROR" cannot verify... something? Please advise.
