A user is uploading information using the embedded spreadsheet, for some reason is getting the following error: "The size necessary to buffer the XML content exceeded the buffer quota" and we have no idea why is this happening. Adding a screenshot of the error.
Can someone please give me some light?
In my case, it was an error on the UD6 member. The name was slightly off but once fixed it worked without splitting the data. So an error within the JE itself is very likely to be the issue - as stated by CarrieS.
