UBB.Developers Forums UBB.classic V6.4 - 6.7 Modifications [6.4 - 6.6] [beta] Shoutbox

Hi - I just installed it and it works fine for "unregistered" users but gives an error for registered users (if logged into the UBB forums).
Here's the error Msg when trying to post as a registered user:
"Software error:
Undefined subroutine &main::md5_hex called at /home/cust1/usr1153/cgi-bin/ubbcgi/ubb_lib.cgi line 376.
For help, please send mail to the webmaster..."


Here\'s the link to Shoutbox on The Other Side BBS

It looks like a great MOD. Just need a little tweaking to include registered users. I have tried both setting by setting the 0 and 1's in the config in the code.

I am calling it from
http://www.theothersidebbs.com/cgi-bin/ubbcgi directory

And have tried moving it to:
http://www.theothersidebbs.com/cgi-bin
directory

Any help from the UBB dev gurus would be more than appreciated !
Thanks in advance...
