We have a solution that the Email Marketing Scheduler doesn't work. This is running version Dw 9.5.5. The following error is returned:
System.MissingMethodException: Method 'Dynamicweb.EmailMarketing.EmailScheduleHandler.Execute' not found.<br/> at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams)<br/> at Dynamicweb.Extensibility.AddIns.AddInManager.InvokeStaticFunction(Type type, String functionName, Object[] arguments)<br/> at Dynamicweb.Scheduling.MethodJob.Execute()
Any help would be appreciated.
