Re: Can't create dashbord

After October 15, 2018, existing vSphere with Operations Management Enterprise Plus licenses will be fulfilled to VMware vSphere Enterprise Plus and VMware vRealize Operations Standard.

With vRealize Operations Standard you cannot create or import dashboards. You need at least vROps advanced to be able to use those features.

For compare of editions have a look at the article below:
