I am having a weird issue for the past two days while uploading image gallery from Lightroom, it stops in the middle and gives me this error message: "An error occurred sending the file: A file was truncated during upload".
This never happened before, I have the latest version of Lightroom. I am using a MAC OS X El Capitan 10.11.4. I spent 2hr on Lightroom live chat, they couldn't find any answers. I contacted my server hosting company, they said there is no interruption in their services.
Anyone has any ideas, suggestions?
Try export rather than upload and then try using a stand-alone FTP app. That will confirm whether or not there is sufficient space on the server to complete the upload.
