Get error every time I publish photos to Flickr:
"Flickr API returned an error message (function upload, message Filetype was not recognised)"
I tried to reauthorise Flickr via app and Flickr website, tried to reinstall app.
Lightroom 4.4.1, OS X 10.10
Same error on LR 5.6 and 5.7, Windows 7 64-bit (64-bit LR installed). Worked fine until a week or two ago. I've seen a report on a Flickr forum of a person using LR 3.6 reporting the same issue in the same time frame.
