Could not load file or assembly 'DotNetNuke.HttpModules' or one of its dependencies. Started By justins123 Hello, I'm new to DNN and upgrading our platform ultimately to 9.10. But I am recieving thebelow error when upgrading from 9.7.0 to 9.8.0 or 9.9.1. The binding in IIS seems to be poitning to the correct place, and I made previous upgrades from 9.2 to 9.7 without issue. It seems the upgrade from 9.7 to 9.8.0 or 9.9.1 (I've tried both) cause this error. Any thoughts on what it might be Server Error in '/DesktopModules/CompanyName/API-Storefront' Application. Could not load file or assembly...	7	4340	3	10/29/2021 12:28 PM by justins123

Upgrading DNN v7.1.1 that uses AD authentication Started By ChrisMc I inherited an old DNN (v7.1.1) website that's setup to use only AD authentication. As it's a live site, I've tried to copy it (database & website), rename the copy and then log in using my normal Windows account username/password and it keeps failing to log me in. I am not able to reconfigure the website so it would allow me to access the site using the normal forms authentication. If I create a new v7.1.1 website login and then add the AD authentication, using the setting found in the or...	4	2174	1	9/23/2021 7:30 AM by ChrisMc

Upgrade DNN 9.9.1 to 9.10.x Started By Michael Tobisch I recently had a problem when upgrading the platform on two sites from version 9.9.1 to 9.10.0 or 9.10.1. When starting the upgrade installer, I immediately got a yellow screen of death saying 'Server Error in '/' Application'. For all the other sites the upgrade worked fine. To solve the problem, I started the installer in a browser on the server to get a more detailled error message, and it said the assembly system.web.http version 5.2.7 or one of its dependencies could not be loaded.
