I have an installation error that I've been trying to troubleshoot (detailed in another thread), but haven't been able to get logging to work, so I have very little to work with (all I get is a blank screen). I'm a developer, so I'm hoping the debug logs might give me some insight.

Here is my log4php.properties file, which resides in the SugarCRM site root folder:

log4php.appender.A2=LoggerAppenderRollingFile
log4php.appender.A2.MaxFileSize=10MB
log4php.appender.A2.MaxBackupIndex=5
log4php.appender.A2.layout=LoggerLayoutTTCC
log4php.appender.A2.layout.ContextPrinting="true"
log4php.appender.A2.layout.DateFormat="%c"
log4php.appender.A2.File=D:/~sites/sugarcrm/log/sugarcrm.log
log4php.rootLogger=debug, A2

Just to be sure it's not a permissions issue, I have created the D:/~sites/sugarcrm/log/sugarcrm.log file and given it and the folder it's in Full permission for Everyone (this is in a Windows environment). The file just remains empty as I click through the installation to step 4. Since I'm running PHP in ISAPI mode, I've been sure to restart IIS whenever changing the config files.

Any clues?

Thanks,
Matt
