Changing "doc.root.folder" property is not working

[NirBY]

After changing Root Doc location, I have got HTTP 404 error.
After added default "docRoot" from the default install, "Execution Reports" has opened, but could not open the testes.

Example for changing done:
"doc.root.folder=/data/docRoot"

Also how do I open logs in Trace?
There is no error/warn in logs.
For trying to open the logs I have used (But it does not worked):
"

Levels: TRACE, DEBUG, INFO, WARN, ERROR

logging.level.org.springframework.web=TRACE
logging.level.il.co.topq.report=TRACE
logging.file=log/difido1.log
"

Also please add an option to Access log.
