DNN9 site "Application Error" Started By jmv412 I'm working through Chris Hammond's 20-part tutorial on YT for DNN9 as I'm new and will be using it at my new job. In video 11, he shows how to create and package a module for use in our local site. The module went through multiple errors, and subsequently made my site stop working. The module did build successfully, but now all I see is the following image and I'm not sure how to even check the error logs. Any help as to how I can at least access the logs would be greatly appreciated!	4	3306	1	5/2/2021 10:18 AM by jmv412
Cannot get the site alias without subdomain to work Started By Tim van der Horst I want to use an ACME bot for free certificates for some of my sites. For that, I must use Azure DNS. It works fine with the alias https://www.aivest.com/ (I can not yet switch to 'only SSL' since some of the sites on that DNN host have no certificate, yet). But I cannot get https://aivest.com/ (or http://aivest.com/) to work properly. Previously, I used the DNS of my registrar domaindiscount24.com, and that DNS service supports HTTP forwarding. All requests to aivest.com were forwaded via 30...	3	1740	2	4/26/2021 11:43 AM by Tim van der Horst
Use of TLS 1.0 and 1.1 Started By Intellicom We will soon be attempting to turn off TLS 1.0 and 1.1 on our servers that host our DNN websites. Before we do so, we thought we'd ask if anyone knew of anything DNN related and/or any DNN modules like Events, FAQ, Form and List, etc. that might not function correctly after those are turned off Thanks!	4	2068	1	4/26/2021 9:37 AM by Intellicom
