503 Error after 2.2.rc1 to 2.2pl upgrade#

I've got a 503 error after upgrade to 2.2pl on IIS7.5, advanced install.

How can I troubleshoot it?

Thanks.

Hi,

Check the following folder for any log files which might indicate what the issue is:

/core/cache/logs/

If there are any errors in the file post it here so I can advise.

Thanks Aaron

I got it figured out Aaron. It was permissions. IIS has me trained now to check permissions.

Now onto ISAPI Rewrite. I think I'll wait until after the site goes live, as right now it's "off" an IP# and ISAPI didn't like the IP# as a base_url.
