If we get the following message when we access our Task List in the console
Cron extension is not running Cron extension has never run or it's not configured well.
To solve this error we will only have to access our Pandora FMS server through a terminal and edit the following file:
/etc/crontab
Adding the following line (where X.X.X.X replace it with your IP address or domain name):
* * * * root wget -q -O - --no-check-certificate http://X.X.X.X/pandora_console/enterprise/cron.php >> /var/www/html/pandora_console/log/cron.log
Save the file and access again to Pandora FMS console, press CTLR+F5 to force the browser cache cleaning, after doing it the warning message should not appear.
