When tried to remove the domain from Plesk Control Panel, the following error message received:
SysUser->systemRemove() failed: usermng failed: Empty input path: (87)
The parameter is incorrect.
The reason for this error is Local path parameter for FTP user of this domain is missing.
To resolve this error follow the steps:
Please, go to Computer Management > Local Users and Groups > Users > select FTP user for this domain > go to Properties > Profile > check if Local path parameter is specified there.
If not, please, specify proper path to this domain directory:
%plesk_vhosts%\domain.tld
