Error preventing me from doing anything

I am not able to access the dashboard or install any plug-ins.

I have uploaded “511483_wpmu-dev-dashboard-4.3.zip” to my cPanel into the plug-ins folder of my active site and unzipped it. However it doesn’t seem to be working. I still can’t get into my dashboard.

When I attempt to bypass the “my websites” and install other plug-ins, I get this error message: “There was a permissions problem or the latest Dashboard plugin is no longer installed on this site.”

I think something might’ve happened when I uninstalled the dashboard plug-in, and canceled my membership about a week ago (Because I really didn’t understand how to use WPMUDDEV services.)

Last weekend, I rejoined and attempted to activate my services again, with no avail.

My domain is the ceramicsstudio.com is already set up as a multisite.

I’m eager to receive your support and to get this going.
