Tried to delete a domain while I was inside the domain folders using WinSCP

[gloveny]

Hi, I tried to delete a domain while I was logged in to WinSCP in one of the domain folders I was going to delete. Plesk said....

Unable to remove hosting: Unable to delete system user: SysUser->systemRemove() failed: usermng failed: usermng: Unable to delete user:

--------------------------------------------------------------------------------

0: /usr/local/psa/admin/plib/class.PhDomain.php:228
PhDomain->reset(integer '0', boolean true, boolean false)
1: /usr/local/psa/admin/plib/class.BsDomain.php:289
BsDomain->reset(integer '0')
2: /usr/local/psa/admin/plib/class.BsDomain.php:283
BsDomain->delete(integer '0')
3: /usr/local/psa/admin/plib/class.BsDomain.php:524
mdeleteDomains(array)
4: /usr/local/psa/admin/plib/class.Manager.php:351
Manager->removeDomains(array)
5: /usr/local/psa/admin/htdocs/domains/domains.php3:215

Now it says that everytime I try to delete the domain.

What can I do , please help.
