Earlier I posted about iRedAdminPro logins being slow.   I made the following changes to settings.py:
AMAVISD_REMOVE_MAILLOG_IN_DAYS = 5
AMAVISD_REMOVE_QUARANTINED_IN_DAYS = 7

I also changed:
SESSION_TIMEOUT = 3600
within default_settings.py.   Since the login was slow this helped our Help Desk employees not have to continually login.

Unfortunately, now iRedAdminPro displays a Gateway Timeout message when accessing the login page.

I've restarted the server without any change.   I tried removing the two lines from settings.py and it now appears to allow logins again.

Is there anything else I can do to speed up login to iRedAdminPro?

Thanks,
Bob
