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'.

In the log there is this error:
2025-11-26 11:28:12.175+00:00 [ukxxlon99ws0144][D:13][T:51][ERROR] Dnn.PersonaBar.Sites.Components.SitesController - System.InvalidCastException: Unable to cast object of type 'DotNetNuke.Security.Permissions.PermissionInfo' to type 'DotNetNuke.Abstractions.Security.Permissions.IPermissionInfo'.

Also in the console, after the unsuccesful attempt, I see a 400 status error on /API/PersonaBar/Sites/CreatePortal:1 that doesn't seem to exist.
See below screenshot.

Could it be that we didn't upgrade from 9.13.6 to 9.13.9 first, but directly to 10.1.2?

Maybe...

We have an suggested upgrade path, version bumps that have known requirements or have received more testing https://docs.dnncommunity...rade-path/index.html

Now I double this would be data related so potentially some dlls might not have been properly replaced. If you go to Extensions > Installed Extensions and then you pick "Perona Bar" in the filter dropdown, do you see the correct version for "Dnn.PersonaBar.Extensions" ?

Thanks Daniel for your reply. It seems I was wrong with the original version, we actually upgraded from 9.11.2 directly to 10.1.2.

We have the backup (before the upgraded) so we chose the safe way and rolled back to 9.11.2 and then upgraded first to 9.13.9 and after that to 10.1.2 - and the problem disappeared. I will keep in mind for the next upgrade that the recommended upgrade path really matter.
