Pete,

if you followed the DNN Platform Suggested Upgrade Path you should have gone from 9.2.0 to 9.3.2 and then to 9.6.0 (or, even better, to 9.10.02).

Anyway, DNN requires .Net Framework 4.7.2 or higher (afair since version 9.4.2), this could also be an issue.

Happy DNNing!

Thanks. I should have clarified 9.2.0 was our original install, but we did upgrade from 9.2.0 to 9.3.2 then to 9.6.2, which appeared to be an acceptable upgrade path at that time. We are targeting 4.7.2 as well.

I have re-synced files and folders in the file manager and compared web.config between this site, and another 9.6.2 site where the file upload is successful, but no leads.

If anyone has resolved a Bad Request error when uploading files I would love to hear your solution. Thanks.

Pete,

please check the permissions in the file system, or if the hard disk has enough space. Also check if the file you want to upload does not exceed the limit.

There was (or is still, I don't know) a "bug" that limits the file size to 28 MB, even if the value in your web.config is higher.

Happy DNNing!

We reapplied permissions for the App Pool. We checked the module and folder permissions in the Site Assets. Plenty of disk space as well. The file size isn't the problem either. We're testing with all file types and sizes. Even a 1KB file gets a Bad Request. Thanks.

Anything in the log files?

Happy DNNing!
Michael

Each time it happens the log files have the same message from my original post:

 DotNetNuke.Web.InternalServices.FileUploadController - System.InvalidOperationException: Bad Request
   at DotNetNuke.Web.InternalServices.FileUploadController.UploadFile(Stream stream, Int32 portalId, UserInfo userInfo, String folder, String filter, String fileName, Boolean overwrite, Boolean isHostPortal, Boolean extract, String validationCode)

Thanks.

This was obviously a problem with 9.6.1 and looks like been fixed.

FileUpload validation code prevents super users from uploading to the default portal · Issue #3850 · dnnsoftware/Dnn.Platform (github.com)

I would suggest to upgrade to the latest version.

Happy DNNing!
Michael

I was hoping to fix without needing to upgrade since we have other installations of 9.6.2 where this issue does not occur, but for this install it looks like we'll have to upgrade sooner than later. Thanks again.
