I've tried to relate wordpress.com stats on my self hosted site to a new api key. After doing so I click on the button below 'add new blog to my account', which gives the error message 'Error from last API Key attempt: Missing API Key' in return. When I therefore try to go back to the old api key, I get the same error message.
From what I understand of this, wordpress.com stats within a self hosted website can only be coupled to the api key of 1 wordpress.com account. Using a new api key isn't possible, but once you've tried doing so, you also can't go back.
I now therefore am at a complete loss concerning how to solve this. Anyone more ideas?
