Hi,

After upgrading to DNN 10.1.1, I'm getting some errors that are referencing: Could not load type 'DotNetNuke.UI.Skins.Controls.Nav'.

From what I understand this is caused by the old Nav.ascx control, but I'm having trouble finding where that is in any of my old skin files.

This is causing errors in the Admin Logs even for pages which have long been hidden from the public.

Where should I look to fix these errors?

Thanks

Tom

Two SkinObjects (WebControls) over 8 years ago: LEFTMENU and NAV

Both were removed when DNN 10 was released. Whatever that output was, you'll need to remove the reference and code and find a different solution to displaying whatever was there before.

You can read more about it here.
