After migrating awstats data from debian i386 to debian amd64, awstat gives me the following error:
/usr/lib/cgi-bin/awstats.pl -config=awstats -update Update for config "/etc/awstats/awstats.conf" With data in log file "/var/log/apache2/access.log"... Warning: Error while retrieving hashfile: Byte order is not compatible at ../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/_retrieve.al) line 331, at (eval 5) line 1
Explanation is here : hashes are not stored in the same way by Perl Storable on debian 32 bit and 64 bit.
The workaround is pretty simple: delete all hashes files, awstats will rebuild them
