Subject ManifoldCF 2.0.1 Reporting Error
Date Mon, 13 Jul 2015 12:43:18 GMT
Hi all,

We have been running 2.0.1 for several months now without issue.
However, for the last few weeks we have had an issue with the reporting part of the crawler
UI.

When you click on a reporting page, it loads okay. When you select a connection and click
continue, a blank grey page loads.
There are no errors in the UI, but a java stack trace (below) appears in the start-webapps.bat
console.

After some time investigating, we can't find any obvious issues.
We haven't made any changes to our configuration for a while, so wondered if you had any advice
on what the issue might be.

Stack Trace:
