Upgrading from DNN 9.1.1 to 9.3.2 Started By JordanM Hi All, Recently upgraded DNN 9.1.1 to 9.3.2 with success until I stopped the app pool, then when restarted pulled an error and wont load. giving me the w3wp.exe error on the server. Something gave me the idea of comparing web.config files (9.1.1 / 9.3.2), i noticed if i ripped these lines out that DNN started loading with no errors. dependentAssembly assemblyIdentity name='Newtonsoft.Json' publicKeyToken='30ad4fe6b2a6aeed' bindingRedirect oldVersion='0.0.0.0-32767.3...	1	2160	0	2/26/2020 3:35 PM by JordanM

Need help upgrading 7.1.1 to 9.4.4 Started By Mark V Hi, we're a small software company that uses DNN to power our 'software as a service' website. But we're not DNN experts, we're only barely competent at administering the website. Those who built the website are long gone, so no one remaining knows how anything was done, or why it was done that way. We're badly overdue for an upgrade, but we've had problems trying to upgrade in the past. What we really need is a short-term contract with a DNN expert who can show us how to upgrade, who can he...	9	4377	3	1/22/2020 1:49 PM by Mark V
Cannot login as Host during upgrading from 7.0.3 to 7.4.2 Started By okuusan703 Hello. I need to upgrade the website that runs DNN 7.0.3 to the latest. Based on this article, I understand that I need to upgrade the website to 7.4.2 first. The website itself is temporarily terminated because it was compromised (all malicious files had already been removed from the server). I found another URL was provided by the hosting company and I'm working on it now. I uploaded all files in the upgrade zip file via FTP and accessed to the site URL. As you know, the Upgrade Wizard page...	3	2630	0	2/3/2020 8:30 AM by okuusan703
