Domain is Not i sync and the domain status is Failed to Delete in POA Customer Control Panel. The following error is shown near the domain status:
Unable to remove last subscription
Example of the error:
If Parallels Plesk Panel uses Power User view it is not allowed to delete the last domain.
To be able to delete the last domain change the interface mode from Power User view to Service Provider view. It can be done in 2 ways:
Login to Plesk CP, switch to Server > Interface Management, change to Service Provider view
Login to Plesk server via SSH and run the command:
# /usr/local/psa/bin/poweruser --off
Please refer to the article https://kb.odin.com/en/9206 for details about Power User View.
After switching the interface mode repeat an attempt to remove the domain via POA CCP.
