解决方法Invalid API key. Please obtain one from http://wordpress.com/api-keys/

最近奇怪seojl.com留言评论的频率突然下降了，刚刚自己在留言板试了一下，结果出现一串“Invalid API key. Please obtain one from,Invalid API key. Please obtain one from http://wordpress.com/api-keys/ ”评论也如此，查了一下才发现是安装了Akismet反垃圾留言插件的缘故， 

解决方法一：删除Akismet反垃圾留言插件

       方法二：按要求去http://wordpress.com/api-keys/注册个号，然后在插件里面找到“Akismet反垃圾留言系统”插件，添写注册号
 

明显第一种最简单删除就OK了

但是因为看到部分留言的朋友出现了其他网站地址的图片头像，怀着好奇，还是去申请了一个帐号

WordPress.com has what’s called “API keys” which allow you to use services like Akismet and WordPress.com Stats built on the WordPress.com platform. This allows you to leverage the power of WordPress.com while still hosting your blog elsewhere.

How do I get one?

For Akismet users: We have free keys and commercial keys available.

For all other services: When you sign up for a WordPress.com account we will email you an API key. If you already have a WordPress.com account, your API key is listed on your profile page, which you can get to by clicking the “My Account” link in the top left when you’re logged in.

Where will my API key be?

It will be in your welcome email. To make sure you get the email, avoid free services like Hotmail and MSN and check your spam filter if it doesn’t show up in a few minutes. (Also, consider whitelisting *@wordpress.com.)

Can I share my API key?

No, it’s like a password to your account.
