sqwebmail renders internal server error when accessed

[jcunningham@mail.vjservice.com]

I'm not currently subscribed so please reply to the emailaddress.  i don't know why sqwebmail is not accessable.
i followed the readme and added the setenv sqwebmail_templatedir to /adir/mywebmail and copied the html templates there.
chmod 755 && chown root.www-data /adir/mywebmail chmod 755 /adir/mywebmail/index.html, restarted everyting and get the same error.  i've been trolling google and havent come up with much so i hope someone can advise me here.

current woody server running qmail, vpopmail, courier imap, pop3 using courier-authvchkpw.  everything is working fine so i don't know why sqwebmail's not happy.  

regards, justin
