I'm in the process of setting up a new wordpress blog (version 2.03) for a friend. I've turned on akismet (version 1.5), but when I enter a wordpress.com API key, it tells me "Your key appears invalid. Double-check it."
This happens with a key I've copied and pasted out of a wordpress.com profile, and also with a second API key which I've tried, which I'm already using successfully with Akismet on my own blog.
Any suggestions on how to resolve this would be gratefully received!
