Recently this error popped up when one of our customers updated their system so we wanted to share how it can be resolved.

 

The following error may occur under ColdFusion Administrator in the scheduled tasks tab:

The error occurred in scheduletasks.cfm: line 188 -1 : Unable to display error's location in a CFML template.

 

This problem occurs if neo-cron.xml file becomes corrupt.

 

Workaround:

Place the following in ColdFusion11\cfusion\lib\neo-cron.xml file and restart the Application Services

<wddxPacket version='1.0'><header/><data><array length='4'><struct type='coldfusion.server.ConfigMap'></struct><boolean value='false'/><string></string><string>txt,log</string></array></data></wddxPacket>


Alternatively, if you have a good backup of the same file you could replace that instead of the above step.

 

We are unable to reproduce any particular events that cause this issue.  If you have run into the problem, feel free to indicate in the comments any potential steps that may have contributed to it.
