Hi,

when trying to download an excel export of a Form's submissions, i'm getting the following error (from error logs):

Note: I even tried giving "Everyone" full access to the file Forms/Handlers/BPInstancesExport.ashx and it is still giving me this error.

An error occurred during download. [LFF4120-ErrorOccurredDuringDownload]
