Unable To Add Domain From Plesk

[Administrator]

When trying to add a domain from Plesk panel, you might receive an error as below.

Error: ProtDir_IIS::update() failed: Add Protected Directory failed: columns siteId, path are not unique (Error code 1)

The above error means the protected directory was not synchronized properly.

Login to your server via RDP & access command prompt. Execute the command below.

"%plesk_cli%\repair.exe"  --synchronize-protected-directories-storage

The above command will synchronize the directories on the server & you should be able to add the domains now.
