I've got a customer who is running Plesk for Virtuozzo.
I've found the components table in the psa database has gone empty on a customer's VPS server. I know it was once populated because he had a site with PHP enabled, however PHP was greyed out when trying to setup a new domain.
I was able to add the PHP record to the Components table by running
INSERT INTO psa.Components (name, version) VALUES('php', '5.0.4');
Anyone know of a method to repopulate this table with all the correct information?
