Stuff…

For some reason Plesk 8.6 backups stopped working on Linux (Ubuntu 8.04.3)  with the error:

Runtime error: Can’t use an undefined value as an ARRAY reference at /opt/psa/PMM/agents/PleskX/SiteApp.pm line 292.

Ran the following command, which, errored at the client that was causing the problem.

/usr/local/psa/bin/pleskbackup -v all /root/backup/test

This errored after when it reached the problem client account.  Then re-running the command whilst excluding the client worked fine.

/usr/local/psa/bin/pleskbackup -v all –exclude=client_account /root/backup/test

Line 292 of SiteApp.pm looks like:

$sappId = $dbh->fetchrow()->[0];

So, along with the name of the perl module and the variable sappId it’s probably a problem with an application on the site.
