Upgrading DNN Blog Module Started By Nick Guzi I’m currently planning an upgrade of the DNN Blog module as part of a broader effort to move my site to DNN 10. The site is currently running Blog module version 6.04.00 on DNN 9.6.2 and includes a number of customizations that were added over time. The site also makes use of multiple instances of the Blog module. From what I understand, both the internal structure of the module and the way multiple module instances relate to each other evolved in later 6.x releases. I’ve also noted that t...	7	256	1	12/29/2025 12:46 PM by Nick Guzi
9.x vs 10.x Started By LeeD Tried to do a 9.x to 10.x upgrade. It sucked (various dependency issues, various error messages and now it's stuck at 68 of installling personabar). So I'm probably going to do a restart and restore and roll it all back. BUT, my understanding is there was a CVE and it was fixed in 10.1.2. Is it also fixed in the current 9.x version and/or was it present in that version. Because security is the prime issue for upgrading here.	3	314	2	1/2/2026 9:38 PM by LeeD
version 10.2.1 Started By cjsailer Hello, I just updated to version 10.1.2 on my DNN instance. I was hoping for the satification of not seeing that red critical flag on the persona bar anymore. However it looks like a new version of DNN was released on 12/31. In the persona bar it's still flagged as critical. But in the release notes on GIT hub I do not see any mention of a security fix. I realize details about security fixes are not released until 30 day afterwards, but I was still expecting to see some mention of it in...	1	261	1	1/2/2026 4:08 PM by cjsailer
Telerik Removal Tool Not Loading (Spinner Loop) in DNN 9.13.4 and 9.13.9 Started By Sandun Amaratunga Hi all, I am on DNN 9.13.9, and previously on 9.13.4. In both versions, when I click Persona Bar → Settings → Telerik Removal, the page never loads. Behavior: A half loading spinner appears on the browser tab, the page refreshes, and the same half spinner appears again. This loop continues indefinitely. Console shows: GET /DesktopModules/TelerikRemoval/API/Remove/Check 404 My questions: Is this a known issue with the Telerik Removal tool in the 9.13.x series ...	2	181	1	11/27/2025 8:05 AM by Sandun Amaratunga
Recommendations for Theme/Skin for a 10.01.02 upgrade Started By cjsailer Hello, I haphazardly performed an upgrade from 9.13.9 to 10.01.02 on a development instance. We have one portal that will partially come up, while almost all others get an IIS 500 error. I've tracked it down to the skin/theme of each portal. Most of our portals are on an ancient version of a theme called multifunction which does appear to be in active support. This skin/theme has a 'left hand' layout. The only portal that came up had an xcillion skin, which works fine in read mode, but when...	12	753	2	11/6/2025 6:28 PM by cjsailer
DNN 10: Redirect loop, and error: Method not found: 'System.Collections.Generic.Dictionary' Started By Tom Melkonian Hi again - Testing DNN 10.1.1 on a test website, in just one of my sites (portals), I'm getting a redirect loop 'site redirected too many times', and in the logs I see this error: Method not found: 'System.Collections.Generic.Dictionary`2 DotNetNuke.Entities.Portals.PortalController.GetPortalSettingsDictionary(Int32)'. One thing about this particular site, is that when you browse to it, it takes you first to the login page, because all pages on this site are only accessible to logged in...	2	318	0	12/15/2025 6:16 PM by Tom Melkonian

Cannot create a new site after upgrade to 10.1.2 Started By Vlastimil Konopisky Hello, we upgraded DNN from 9.13.6 (which was working fine) directly to 10.1.2. After that everything seemed to work ok, but recently I found out I cannot create a new site anymore. During the creation process (showing blue progress bar on the top) DNN returns an error below: Unable to cast object of type 'DotNetNuke.Security.Permissions.PermisionInfo' to type 'DotNetNuke.Abstractions.Security.Permissions.IPermissionInfo'.
