I use Wordpress with SimpleViewer. For some time, it no longer works and I get the following error message: Flickr User not Found.
I checked the Flickr User Name in SimpleViewer and Flicks: it is the same and has not changed, and it worked for 3 years with no problem.
SimpleViewer version: 184.108.40.206
WordPress version 3.9.1
