I alr donate the coreprotect and got the donation key, but when I put the donation key into config.yml and restart the server, it still reminds me that “Invalid Donation Key”
How can I solve it?

Please ensure you’re using the latest version of CoreProtect, and are entering the donation key correctly in the configuration file.
