title: SharePoint custom timer job execution issue
body: <p>We have developed a timer job for SharePoint 2013 in Visual Studio 2012. It is scheduled to be running between 7 AM to 7:15 AM. We have deployed the timer job using PowerShell. In code we have added <code>PortalLog.LogString</code> to log messages in SharePoint error logs at the beginning of the timers execute method.</p>
  
  <p>Under Site Collection we can see that it is deployed and activated. The scope of the timer job is set to Site in VS. We can see the timer job which is deployed in the review job definitions in central admin. But, cannot see it in scheduled jobs. When we go to edit the timer job via review job definitions, and hit 'Run Now', we cannot see any messages in the error logs that we have programmed using <code>PortalLog.LogString</code>.</p>
  
  <p>What could be the issue?</p>
