We have tested a couple of modules like Axon and your module seemed to be a bit more reasonable except for this bug problem where after scheduling a newsletter for my opt-in list to be sent right away, I tried going back to the control panel settings but some how the module had locked me out from accessing the features. We got an "Object reference not set to an instance of an object" error every time we click on the Opt-in AdvanceMail Control Panel.

We are using DNN 4.9.2 and Opt-in Email 4.2.

Please help as this is a critical point for this project and we had been delayed for 2 weeks now, the scheduling is the last stretch and we need to make it work.

We've got the same issue here.

it says:

DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at Dataspring.DNN.Modules.OptInAdvanceEmail.__OptInDashBoard.GenerateCurrentDashboard()


What should I do?

(DNN 5.6.0 and Opt-In 4.2.0)

In the scheduler it says:

There are newsletters scheduled for distribution however there are pending distributions that are either still processing or have failed. You must clear these distributions within the schedulehistory table before the scheduler can continue. Double check to make sure your schedule is processing properly under Host, Schedule, and that your distributions are not overlapping each other. If you continue to receive this notice you should increase the time span for the schedule. You can also check the [ScheduleHistory] table within DNN to clear out previous distributions history if necessary.

So what does this mean, I should clear something in the schedulehistorytable?
What should I clear exactly?
I think this happende when it was sending a newsletter, so should the newsletter be resent?

Yes... You can type this in under Host/SQL:

Truncate Table ScheduleHistory


This will tell the system that there are not other pending items running... If you continue to have this problem or it comes back there is probably a bigger issue to look at. Also please open a support ticket via the DNN Store and we will make sure you have the very most recent patch/update.

Thanks!
