Errors Returned

I tried the plugin with basic auth and digest and received the following errors. Any suggestions on how to resolve these would be appreciated.

for basic auth – Use of uninitialized value in printf at /usr/local/nagios/libexec/check_allnet4500.pl line 286.
Sensors OK – 0 sensors checked:

For Digest – Unable to recognise encoding of this document at /usr/lib/perl5/vendor_perl/5.8.8/XML/SAX/PurePerl/EncodingDetect.pm line 96.
No semi-colon found after entity name [Ln: 33, Col: 81]
