hi

when i upgrade DNN 6.2.5 to 7.3 I get arror at Host Seeting Page:

Selection out of range Parameter name: value

and in Event Log page I  have this exception:

DefaultDataProvider:DotNetNuke.Data.SqlDataProvider, DotNetNuke
ExceptionGUID:fb85216a-8cba-4818-ad6e-350b74b5df1f

when I was tried to trace and  debug i was found this error is for this line in the hostSetting.ascx..cs file:

 editContainerCombo.RootPath = SkinController.RootContainer;

when I comment that line, this page is work without any error; why?

Somewhere in the 7.3 upgrade step, DNN deletes the default skin selections from the HostSettings table.  Then , due to a databinding problem with the new DNN ported version of the Telerik library, the skin drop down boxes on the Host Settings pages don't load, which causes the error shown above.

 To fix, simple add back the four records to the HostSettings table:

DefaultAdminContainer	[G]Containers/Gravity/Title_h2.ascx	False	1	2012-12-01 00:17:42.830	1	2012-12-01 00:17:42.830
DefaultAdminSkin	[G]Skins/Gravity/3-Col.ascx	False	1	2012-12-01 00:17:42.830	1	2012-12-01 00:17:42.830
DefaultPortalContainer	[G]Containers/Gravity/Title_h2.ascx	False	1	2012-12-01 00:17:42.830	1	2012-12-01 00:17:42.830
DefaultPortalSkin	[G]Skins/Gravity/3-Col.ascx	False	1	2012-12-01 00:17:42.830	1	2012-12-01 00:17:42.830

I don't the actual values are important, but to be safe, make sure the skin and containers actually exist! you can change it later after the page loads correctly.

This problem has royally screwed my site and replacing this lines in the database has done nothing at all!!! I dont know how to proceed unfortunatley
