We're using DNN 5.1.4. We've tried in a few different browers (FireFox 3.5.5 and IE 7.0.5730.13), and the File Manager does not open the file structure sub-folders when clicking on the folder icons. Nothing happens at all.

The error console is showing:

Error: dnn.controls.controls[m_sDNNTreeID] is undefined
Source File: http://www.cerfdev.org/Admin/FileManager/tabid/52/portalid/0/Default.aspx
Line: 691

The context around that error is:

function getSelectedTreeNode()
{
    if (dnn.controls != null)
        return dnn.controls.controls[m_sDNNTreeID].selTreeNode;   
    else
    {
        eval('var oNode = ' + dnn.getVar(m_sDNNTreeID + '_selNode'));
        return oNode;
    }
}


Ideas?

We're using the default Minimal Entropy skin as the host skin where we're having the issue. Werid.

I guess we can dive in and see if there is some other JavaScript at play.

check your site for a folder called "portal" or containg special characters like '.

Rename folder and perform a recursive sync in Admin :: file Manager.
