(Solution at bottom :-)

 

After upgrading from version 4.8 to the newest version 5.x, we got follwing exception when accessing frontpage of our DNN site:

 

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.

    --- End of inner exception stack trace ---

Solution:
The solution was simple. Go to the DDN database table "HostSettings" and set EnableAjax to 'Y'.
I havent researched why this is necesary yet, but i recon IconBar in v5.x has some kind of dependcy to MS Ajax.

I hope this will help someone out there, we had trouble finding any answers to the problem. :-)
