Hello!
I have just upgraded Openfire from 3.6.4 to 3.7.0, it looks like everything works fine, but logging doesn’t and the only log I can see since the upgrade is a stderror.log file in the openfire’s log subdirectory which contains this error:

log4j:ERROR Could not instantiate appender named “openfire”.
log4j:WARN No appenders could be found for logger (org.jivesoftware.util.log.util.CommonsLogFactory).
log4j:WARN Please initialize the log4j system properly.
I have tried to clear log files through the admin console, they were cleared successfully but they are still empty even after I turned on debugging and intentionally caused failed logins which I remember previously were logged in the error log.
Does anyone have any suggestions on how to fix this issue?
