Issue "The license key is invalid." after deleting backups

[Robin Edwards]

A couple of days ago, I deleted some of our old backups from /var/lib/psa/dumps/domains/{sitename}/. I deleted them physically on the server, just deleting the big files.

Today, when I tried logging into Plesk, I get this error (and am unable to do anything else):

Error: The license key is invalid. In order to use Panel, please obtain and install a new valid license key.
The amount of currently used resources overrides the limits defined by your license.
The number of websites hosted on the server exceeds the limits defined by your license. You have 9 sites hosted; your license allows hosting only 0 sites.
The number of served email accounts exceeds the limits defined by your license. You have 26 email accounts currently served; your license allows serving only 0 email accounts.
​

I've tried deleting registry.xml, and it seems to re-generate successfully (but the problem persists).

Does Plesk have any logging that could give me an idea of whether these two things are related, or is there anything else I could try?

Thanks in advance for any help,

Robin

Looks like that you need re-install your license key - https://kb.plesk.com/en/124920
