Upgrade an existing install documentation?

Could you please change $development to true in config.php around line 43.

After that, there is a log file in the error_logs folder, and the log messages in appache error log are mote verbose.

So far I don't have a clue why its not working.

FIXED!
I've found the issue. It was a permissions issue on the www and html parent directories, they were still root root and not apache apache.

chown'd them to apache apache and rebooted the server and voila!! working!

thank you for your assistance Tom!

Much appreciated.
