A fatal error has occurred webmail problem

[ridgey]

Hi there,

Just upgraded our plesk server from 7.5.4 under RH9 to 7.5.4 under RHEL4.

Now when a customer tries to use webmail the following error comes up:

A fatal error has occurred
DB Error: connect failed
Details have been logged for the administrator.

All other sites using databases works fine, any assistance appreciated.

Regards.
