Not allowed to access excluded_users

I get the same error message also when I use the config page of the module, but on a blank page.
Seems the logging is active, but I also get tons of errors on any page I try to view, when the module is active and properly configured.
These are the error messages I get:

* warning: in_array() [function.in-array]: Wrong datatype for second argument in /var/www/virtual/***/htdocs/firestats/php/db-common.php on line 241.
* warning: unpack() [function.unpack]: Type n: not enough input, need 2, have 0 in /var/www/virtual/***/htdocs/firestats/php/ip2c/ip2c.php on line 230.

The second warning is repeated about ten times.

Is it a firestats bug or what?

about the problem with the error message (not allowed to access excluded_users) - please open a bug report at http://firestats.cc
about the second problem with the db-common error, please open another bug report at http://firestats.cc
about the third problem, it sounds like a known problem with PHP 5.2.1 on 64bit systems.
see this: http://firestats.cc/ticket/264

thanks, i'll switch to stable and post a bug report
by the way, i don't think i'm on a 64bit machine, and i'm running on PHP 4.4.6-0.dotdeb.2
when I was searching for some info, i found that bug report on firestats' site, but it's not my case...
hope the stable version works..
thanks again!
