Hi Rob!

Does this only happen for scheduled newsletter? How do you mean that the "groups are not shown"? Where are they not shown?

This error NewsletterStudio: Cound not load subscription-provider: UmbracoNewSubscriptionProvider, type: NewsletterStudio.Bll.Providers.UmbracoNewSubscriptionProvider, NewsletterStudio.

Indicates that something is wrong with the configuration for the subscriptions providers. There is a default configuration here that you can look at: https://gist.github.com/enkelmedia/17f569bb04886a8b4ab1b2bddcb09bff

Hope that this helps.

Hi Markus,

The members go missing at random intervals. By missing I mean the circled area is not there when going to send an email immediately, or scheduling for later.

Editing the main web.config seems to bring them back?

I'm using the default config (below)

Hi!

So you mean that the list of Member Groups are empty at random times?

Is there a way to replicate this or does it just happen randomly? The list is populated using the Umbraco API when the page is loaded so it's hard to say why this is happening... =/

// m

Question:

Are you sure that this line is always the same?

<provider name="UmbracoNewSubscriptionProvider" type="NewsletterStudio.Bll.Providers.UmbracoNewSubscriptionProvider, NewsletterStudio" />

No build configuration etc that changes this?

I would like you to have a look in the trace-log when this happens next time to see if we can get any clues from any error that might happen.

Yes config is the always the same.

Next time it happens I'll send over the full trace log for you to review.

Thanks Rob!

Sorry for this issue, we'll make sure to figure out what's wrong and solve it together.

Cheers!

Hi!

Thanks for sharing the trace log. I looks like the constructor of the UmbracoNewSubscriptionProvider fails to load and the result of this attempt is then cached until the next app-pool reset.

In the constructor we're just getting the memberservice and the membergroupservice, I'm not really sure why this happens at random times.

OR does this happen all the time for you? I've tested but I can't reproduce the issue which makes it hard to debug. Any clues around this would be great - are you sure that your Umbraco site is loaded or might it be that the app pool has been recycled and that Umbraco has not been initialized?

Hi!

An update on this one, I've managed to reproduce your issue.

We'll have to provide a fix for this in the next release, which should be something like a week away.

Hi!

A new release is out: https://www.newsletterstudio.org/download/

Here we're using a surface controller to send insteed of the old .aspx-file. This solved the issue with the Umbraco-dependencies that was returning null.

Please give it a try and let me know if it works =D

is working on a reply...
