We are using Oqtane 3.4.2 and 2sxc 15.08.00. We have configured a contact form. If we send a Message we receive an error "An unexpected error occured while sending. Please try again. If it fails again, please send it by E-Mail.".
We try debugging. The exception is throwing in the method "FormController.ProcessForm()". The line is "foreach(var file in...". We have configured no files to upload.
