I just recently upgraded my installation to DNN 5.5 and it seems to have caused a problem with my DMX (version 05.02.09) module. When I attempt to open the Main Options under the Admin member it throws the following exception:
Method: Bring2mind.DNN.Modules.DMX.Common.DNNModuleController.GetModuleInstancesByDefinition
StackTrace:
