I have a container that I used ever since my site is built. But just yesterday, the container suddenly become unusable. When I apply the container to a module, I receive these exceptions in my event viewer, 

AssemblyVersion: 6.1.1

InnerException: Unhandled Error Adding Module to ContentPane

Method: DotNetNuke.UI.Skins.Pane.LoadModuleContainer

StackTrace:

Message: DotNetNuke.Services.Exceptions.ModuleLoadException: Unhandled Error Adding Module to ContentPane ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.UI.Skins.Pane.LoadModuleContainer(ModuleInfo module) 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)

And on the module that was applied with the container, I receive 3 error message that is only visible when logged in as admin

When I remove the title token from the container, the modules load fine, but I have a similar container that has almost the same structure as this module and it is not giving any problem. Is this some kind of conflict or what?
