# API Key is not valid

 * On settings, when I added my Flickr API key, user ID, etc, it keeps returning
   an error message with ‘API key is not valid’. Any idea why this could be happening?
   Thank you

 * Oh and I have tried the alternative PhpFlickr version from the settings with 
   the same error message unfortunately…

 * Have you checked you didn’t accidentally include a space when you copied and 
   pasted it? I had a trailing space in mine that threw an error until I spotted
   it.
