Client denied by server configuration :
[Sun Dec 07 14:04:38 2009] [error] [client 127.0.0.1] client denied by server configuration: /home/username/public_html/catalog/admin/index.php
If you get this error then you need to check the .htaccess file under the respective directory (here catalog/admin) and there you need to comment the rule “Deny from all”
#Deny from all
That’s all this will do it.
