Akismet

[agroinnovations]

Wondering if anybody has had any problems configuring Akismet.  I can get it installed with no problems, but when I enter my new WP API I get

"The key you entered is invalid. Please double-check it."

I've triple checked it, to no avail.  Did I configure something incorrectly?  Is this a common problem?

It has worked for me in the past I'll have to check again.
If you are using WPmu know that every user will have to enter their akismet key for their blog.
