Update: This issue was fixed in the 7/12/2019 update
When a user tries to upload a document to a Portal Document they receive a 'Permission Denied' error. This happens when a user, or a group a user belongs to, has previously had permission to the DCS table. Normally, only Read, Insert and Update to Portal Options should be necessary to manage Portal Documents. If the permission to the DCS table is deleted, the user can upload documents. This may be done through SQL.
Besides deleting the UGP record, be sure to remove any permissions for Users/Groups to DCS in the Security area.
When will this be fixed?
