Having picked up code left from another programmer one of the first things I did was replace all the instances of 'YourCompany' with the actual company name.
Since then I have updated the code and DLLS on the server and my test server and all works fine. However, today I see multiple entries in the event viewer

Message: System.Exception: Error Creating BusinessControllerClass 'YourCompany.Modules.TTSTimeClock_LogInMod.TTSTimeClock_LogInModController' of module(TTSTimeClock_LogInMod) id=(409) in tab(81) and portal(0) ---> System.ArgumentNullException: Value cannot be null. Parameter name: type at System.Activator.CreateInstance(Type type, Boolean nonPublic) at DotNetNuke.Framework.Reflection.CreateObject(String TypeName, String CacheKey) at DotNetNuke.Services.Search.ModuleIndexer.GetModuleList(Int32 PortalID) --- End of inner exception stack trace --- at DotNetNuke.Services.Search.ModuleIndexer.GetModuleList(Int32 PortalID)

I traced back to the entry in the Controller class setting in the module definitions. On my local machine I replaced the text in the definition with the correct company name and it clears the event error but on the live site the settings are disabled?
How can I get them enabled so I can change them
thanks

Hi Mitchel,
Thanks for the reply. 
These modules are not deployed as a redistributable module, they were defined in the portal and are manually updated each time a change is made. As in I replacae the code in the desktop modules folder and the DLL's in the bin.
