Switched to use the "AspUploadProvider", but no change. Now cannot switch it to any other provider. The is also no web.config menu/settings under the "Admin" menu.

Everything was working, no changes were made to DMX, then nothing would upload. At the same time, we have had issue with uploading through the DNN File Manager and Telerik Image Manager.

The following entires are in the web.config:

















Using latest version of iFinity URL Master, but not sure if its related. Were running 5.3.3, upgraded to 5.3.5 in attempt to resolve issues, no luck. Originally running DNN 5.5, upgraded to 5.6, then upgraded to 5.6.1 about 5 days before issues started appearing.

Please advise. No real issues with DMX until now. As Murphy would have it, launch of site is in 4 days.

The following entires are in the web.config:

Hi Brendon,

Sorry to hear about your deadline on this. One thing to note: it is thrown in the viewstate handler of the permission grid. I believe DNN 5.6.1 did something to the viewstate handling but I need to research further. I have *not* seen this error, but I am not excluding this is a DNN 5.6.1 error either. Check for this bit in the web.config
viewStateEncryptionMode="Always"
remove it and try again. Did it fix it? please let me know. If so I have something to go on with the DNN security team (I'm pretty sure this change came from a security issue).
