Breaking change in DNN 7.0.0? - Error getting List of Stream.

[skarpik]

DNN v7.0.0, 2SXC v11.4.0, Bootstrap 4 Instant theme (v4.10.0)

I created a new DNN installation and added a page to test the Events and Courses module. I dropped the Events and Courses app onto the page and I get the following error. Tested other 2SXC apps and content on another test page - all works perfectly.

Tested the Events and Courses module with DNN 9.6.2 and it works perfectly. It looks as if there is some breaking change in DNN 7.0.0.

Here is the error message from the DNN 7.0.0 website:

I assume you mean DNN 9.7, not DNN 7 - correct?

I'm almost certain you have this issue - it's a bug in DNN 9.7 they are still trying to fix https://github.com/dnnsoftware/Dnn.Platform/issues/4003

Yes - DNN 9.7.0 (too many Zoom meetings, my brain has gone soft). And yes, the DNN bug that you reference is likely the problem. The only difference is that my bug occurred with a brand new DNN 9.7.0 installation rather than as a by-product of an upgrade from 9.6.2. Almost certainly the same underlying problem. Thanks for the quick reply.

np. best join that thread to ensure it will be fixed before 9.7 is released 👍
