WHMCS Cron Job is not completing

[insider1]

Hello,

 

I have noticed that on our system in the last two days WHMCS cron job is not completing and we have not receiving Cron Job email.

In the logs I see:

Cron Job: Starting

 

Before a two days everything works normally.

Cron Job is done until: Sending Invoice Reminders

And thats it.

 

Any suggestions how to fix this or how to detect causes of this cron job not completion?

 

Thank you for any help.

With the big help of WHMC stuff I have found problem. There was an error in one of payment processor modules which shows up only when running cron job. And PHP errors showing was dissabled in the WHMCS configuration.php file. So, even PHP errors showing is enabled in the php.ini, WHMCS not shows any errors.
