Why has gitlab denied me access to create more repos?

I’m using gitlab on a home server for personal stuff and I created a repo today and got this message:

You won’t be able to create new projects because you have reached your project limit.

Why is that? How can I stop that happening? I’m not a company or anything just fooling around on my home lab.

I reset my admin password with https://docs.gitlab.com/ee/security/reset_root_password.html

and then logged in to https://server/admin and changed my user limit
