WP Admin - Sorry, you are not allowed to access this page for Plugins Page

Hey guys,

I am just setting up WPMUDEV plugins on a staging site and I get this error when I try to browse to the plugins page.

I have tried the suggestions here, but no luck:

I am still able to install plugins on the site via your website so it's not urgent. But it would be nice to figure out what's wrong.

I'll grant you guys access to the site in case you want to check anything.

Thanks,
Paul
