PleskFatalException - Unable to remove Domain Templates/Clients

[Niivo]

Hello,

Last night I did a clean install of Plesk 8.3 on CentOS 5.

I'm running into the following error when trying to remove domain templates:

-----

ERROR: PleskFatalException
Up LevelUp Level
TemplatesList::remove() failed: TemplatesList::getRepositId_() failed: Unable to define templates

0: /usr/local/psa/admin/plib/common_func.php3:158
psaerror(string 'TemplatesList::remove() failed: TemplatesList::getRepositId_() failed: Unable to define templates')
1: /usr/local/psa/admin/htdocs/creation_templates/dom_templates.php:58

---

When removing the templates, the name of the template is removed from the list, however the checkbox remains to try and remove the template, and the above error is generated.

This issue is also stopping me from removing a Client from within Plesk, with the following error being presented.

-----

Error: Unable to remove client: Client: Unable to remove client templates: TemplatesList: Unable to remove templates list:

Has anyone else come across this issue? Or know how to go about fixing? Any help would be very much appreciated.

Cheers,
James
