Errors for PLESK_MAILNAMES_D

[RobertMidd]

During an upgrade to Plesk 9, I got several errors stating Configuration variable not found: PLESK_MAILNAMES_D

Although the upgrade completed this error is still given when I try to use Plesk and the Plesk admin panel does not load.

How do I resolve ?

Well I tried it again by restoring 8.6 (which works fine) and upgrading to 9.0.0 but I get the same issue.

This is on CentOS5

Anyone ?

not sure if this is the solution but it appears to have worked.
I edited the psa config file (/etc/psa/psa.conf) and set PLESK_MAILNAMES_D to the same value as QMAIL_MAILNAMES_D
