can not create database

We install trial 3.1.1.7 version on Red Hat Linux 7.3
We can not create database via Hub Manager: after clicking on Databases node,
at the left bottom frame we do not have create database button etc.
(only refresh button)
Could anybody help us ?

Hi Fish,

Have you checked the installation logs to make sure that there were no errors?

What browser are you trying to use with the SMH?

Kind regards,

Simon
