Hi Peter,
After upgrading to DMX 6.1.10 on a DNN 7.3.2 installation, we're now getting a Letterbox exception "Unhandled Error Adding Module to ContentPane". Here's the full stack trace:
DotNetNuke.Services.Exceptions.ModuleLoadException: Unhandled Error Adding Module to ContentPane ---> System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at Bring2mind.DNN.Modules.DMX.LetterBox.PortalModuleBase.UploadProvider()

at System.Web.UI.Control.InitRecursive(Control namingContainer)
at System.Web.UI.Control.AddedControl(Control control, Int32 index)
at DotNetNuke.UI.Modules.ModuleHost.InjectModuleContent(Control content)
at System.Web.UI.Control.EnsureChildControls()
at DotNetNuke.UI.Containers.Container.get_ModuleControl()
at DotNetNuke.UI.Containers.Container.ProcessModule()
at DotNetNuke.UI.Skins.Pane.InjectModule(ModuleInfo module)
--- End of inner exception stack trace ---
at DotNetNuke.UI.Skins.Pane.InjectModule(ModuleInfo module)
at DotNetNuke.UI.Skins.Skin.InjectModule(Pane pane, ModuleInfo module)
This then causes another General Exception:
System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at Bring2mind.DNN.Modules.DMX.LetterBox.PortalModuleBase.UploadProvider()

at DotNetNuke.UI.Containers.Container.get_ModuleControl()
at DotNetNuke.UI.Containers.Container.ProcessModule()
at DotNetNuke.UI.Skins.Pane.InjectModule(ModuleInfo module)
which results in a Module Load Exception:
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.
at Bring2mind.DNN.Modules.DMX.LetterBox.LetterBox.Page_Load(Object sender, EventArgs e)
--- End of inner exception stack trace ---
which leads to a Page Load Exception:
DotNetNuke.Services.Exceptions.PageLoadException: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases. ---> System.Web.HttpException: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.

at System.Web.UI.Control.FindControl(String id, Int32 pathOffset)
at DotNetNuke.Services.Exceptions.Exceptions.ProcessModuleLoadException(String FriendlyMessage, Control ctrl, Exception exc, Boolean DisplayErrorMessage)
--- End of inner exception stack trace ---
which causes a page redirect loop on the url (e.g. "https://www.domain.com/Default.aspx?tabid=287&def=ErrorMessage")
which causes Firefox to display:
"The page isn't redirecting properly.
Firefox has detected that the server is redirecting the request for this address in a way that will never complete."
I see you have a warning about upgrading to DNN 7.3 in another forum post. We had already upgraded and were using a previous version of DMX (I believe it was v6.1.6) on DNN 7.3.2 without problem. So it seems that something about the upgrade to DMX v6.1.10 may be the source of the problem. We're using LetterBox v1.4.0 from 2012. I don't see any later version, so I assume that's ok, but perhaps there's a problem in that module with respect to DMX v6.1.10.
We're doing the upgrade over the weekend to assure that we can get it working by Monday morning Eastern USA time. Any help or guidance you can give us would be appreciated. Otherwise, we'll roll back.
Thanks!
