I am currently trying to upgrade my DNN application from version 9.0.1 to version 9.0.2. I have downloaded the upgrade.zip for version 9.0.2 from https://github.com/dnnsoftware/Dnn.Platform I then exported the content and copied it to my website folder. When I then go to my website (which only runs locally) I get a DNN error without any text or information. It says DNN Error only on a grey background in the browser. Using the developer tools I could see that the following error is displayed in the console: 

GET http://local.sylaender.me/Portals/_default/default.css net::ERR_ABORTED 404 (Not Found) - UpgradeWizard.aspx:8

I have looked at the UpgradeWizard.aspx file. It refers to a default.css which is located in the folder /Resources/Shared/stylesheets/dnndefault/7.0.0/. I copied it and pasted it into the directory /Portals/_default/. The error in the console of the developer tools did not come with it any more, but with the call of the page DNN Error still shows without any information. In the console of the developer tools there are no more errors to see.

Try looking at the EventLog table in the database to see if you're getting a specific error

select top 15 * from eventlog order by logcreatedate desc

select * from exceptions

I think that's the query to use, see if that gets you any additional info that is helpful

  • So the first query gives me besides hash values the following useful information: `LogTypeKey: PAGE_LOAD_EXCEPTION; LogConfigID: 6; LogProperties: some xml`. Everything else is not very useful. The second query gives the following useful information: `Message: Access to the path "C:\inetpub\sylaender.me\Portals\0-System\Cache\Pages\" was denied;` – Ali Aug 30 '19 at 19:42

Sorry but everything didn't fit in the first comment. – Ali Aug 30 '19 at 19:45
