And I too have the same problem using version 2.8.1:
I get this on the dashboard of my blog/website located at 10.0.11.9:
“The WordPress.com Stats Plugin is not working because it needs to be linked to a WordPress.com account.
Enter your WordPress.com API key to link this blog to your WordPress.com account. Be sure to use your own API key! Using any other key will lock you out of your stats. (Get your key here.) API Key:”
I get my API key from my account at WordPress.com and I put it in. Then I get:
The API key “XXXXXXXX” belongs to the WordPress.com account of “solarboy45”. If this is not your account, please re-enter your API key.
Add new blog to my account
Do this if this blog is new or has never been associated with your API key. This blog will be added to your WordPress.com account.”
I follow the instructions, I put my API key in again but I just go back the original prompt:
“The WordPress.com Stats Plugin is not working because…”
What is the process that requires a key? I sign into my blog at 10.0.11.9 using admin, do I have to use the same accout on my blog as on WordPress.com? What if I can’t? The API key that I’m using works fine with Akismet.
Thanks.
