This error usually occurs when there is a custom document object created.
You cannot delete a custom object class if there are instances of that custom object anywhere on your site. You must first locate and delete from your site, all instances of the custom object before you can delete the custom object class. Also, deleted instances in the trashcan will need to be expunged.
Any objects that have the custom property applied, must be deleted and expunged from DocuShare.

b. Under Type of Object check to see if there are any instances of the Custom Object. If there are take note of how many there are.
Note: You may need to check the site statistics again after you believe you have deleted all the custom objects to be sure that it is at 0 before trying to delete the custom object from DocuShare again.

a. From the DocuShare Home Page, type the custom object name in the search box. (case sensitive)
