ERROR In memory log disabled

I got following error in servoy 5.2, when see the trace in the server admin page. I checked the servoy.properties file but mention suggestions are in the file.

http://localhost:8000/servoy-admin/log

Please help me to solve this issue.

In memory log disabled; to enable add the following lines to the servoy.properties file:

log4j.appender.configservlet=com.servoy.j2db.util.SlidingWindowAppender
log4j.appender.configservlet.layout=com.servoy.j2db.util.Log4JHTMLTableLayout
log4j.appender.configservlet.layout.dateTimeFormat=yyyy-MM-dd HH:mm
log4j.appender.configservlet.threshold=INFO
log4j.appender.configservlet.windowSize=1000

Also add the configservlet appender to the root category:

log4j.rootCategory=INFO, file, configservlet

Thank You

that should work
Does a default servoy.properties file work for you? then you can look what is different.
Somehow the logging is not configured correctly
