I recently updated one of my Gadgets blog to WordPress 3.0. After updating the blog to latest 3.0 version, I enabled multiple site network option and for that I had to disable all the WordPress plugins. After making my WordPress 3.0 blog WordPress MU compatible blog, I reactivated all the plugins. To make my WordPress.com stats plugin work, I had to add the WordPress API key again and once I added it, I started getting 400 Bad request Nginx error. Earlier I thought it’s because this plugin is not compatible with WordPress 3.0.
After bit of research I realize this 400 bad request error is because of error in putting API key. I have added one extra space after the API key and that’s why it is giving the error. If you face the similar issue, here is workaround for the same:
- Deactivate WordPress.com stats plugin
- Activate WordPress.com stats plugin
- Add WordPress API key (Take care of space or any extra character)
Your WordPress.com will not be giving any error after this. Do let us know if this helped you or you still getting the same error?
