Hi, we are using Q3 FileExplorer & .net 2 framework on a Windows 2003 server. We have the view, upload, delete paths set correctly, but the upload button is inactive. On the server, the security settings the Asp.net machine account, the Network and Network Service accounts have FULL CONTROL permissions applied at the root level of the site, with 'Allow inheritable permissions' Checked. I have verified that the sub folders where we are trying to upload files indeed have these permissions set as well. Does anyone know what would cause this and what I should do to get this working. I am puzzled as we have other sites on the same box configured the same way, and the file Explorer works fine (except those use Q2 Telerik rather than Q3 but I dont think this is the issue). Thanks in advance for any help on this.
