Api key problem

i just set up a wordpress blog on my site, and it’s saying my Api key is incorrect, but it’s the one i just got from my new account on WordPress, any idea why this may be and how i can resolve the problem.

My blog section’s adress is

http://www.seewhitstable.com/Whitstable-Blog/

The section isn’t linked from the main site’s side yet, but it is linked to main site.

Thanks for your help,

Tom West
