Epi 11 - Unknown server tag error



We are in the process of upgrading to Episerver 11.3.3 and everything seems to be working smoothly (after sorting config issues) except for several tools in the Admin section. We are receiving errors that look like this:

Unknown server tag

I'm guessing we are lacking some sort of configuration?

Do you have this line in web.config under system.web->pages->controls ?

<add tagPrefix="EPiServer" namespace="EPiServer.Web.WebControls" assembly="EPiServer" />

We do, yes.

Try adding 

<add tagPrefix="EPiServer" namespace="EPiServer.Web.WebControls" assembly="EPiServer.Cms.AspNet" />
