I'm having the same problem with a "old" 4.8 umbraco site...
When trying to upload file as "file" or "image" I get this error

Ok, so did this just start to act up all of the sudden? What changes were made before this started to happen? Or have it been acting like this all the time? Are there other parts of Umbraco that is acting weird? If so it might be worth checking if the webserver is running out of disk-space.
Hmm, what version did you upgrade from? And how did you do the upgrade? Did you merge the files in the /config/ folder as well? If not this could be the reason since some things might have changed in EmbeddedMedia.config and UmbracoSettings.config if I remember correctly.
In newer versions CE SQL is being used - Don't know if it's possible to somehow migrate from the old embedded db to CE SQL.
Yeah it can be uphill at time - Especially if one is used to (and comfortable) using XSLT.
But don't know if you're already using Visual Studio...but if you're not then it might be worth considering since the intellisense support helps a lot. I also think Webmatrix has some intelissense support.

Hi Klaus
Does this happen when you use the upload datatype or when you're uploading media in the media section?

Hi Crawn
Ok, so does it happen when uploading any kind of file? What type of file are you trying to upload? .png,.svg,jpeg, .webm?
And is the size larger than 4 mega byte?
/Jan
Hi Jan
Tried png, pdf, jpg, gif... all sizes from 50k to 1 mb...

Hi Bent

/Jan
It started just after upgrading to 4.8... To my knowledge no other problems with Umbraco.
I would update the solution, but the site uses the integrated DB and can't find a newer version that supports this...

Hi Jan
I did the 4.7.2 to 4.8 upgrade (following the guide and version specific gude to the point)
/Bent
I merged the config-folder again and now it works... Must have missed something in the first try :P
Thank you for your help Jan!
Hi Bent
Happy I could help - And happy coding! :)
/Jan
Thanks... Will be needing it!
Just dived into Umbraco 7... OMG! Razor is killing me!

Hi Bent

I also tend to have the cheat sheet nearby when doing Razor https://our.umbraco.org/FileDownload?id=8865
Hope it can help a bit :)

is working on a reply...
