Feedburner Not Working After Installation of WP SEO by Yoast

Hello,

Since installing and activating Yoast’s great plugin, feedburner has not picked up or sent out any notices when I publish a post. Four posts so far have gone unannounced.

How can I fix this?

I’m pretty much of a newb, so if this involves any coding, I need to know what document to use and where, in that document (after ________ and before ________)I would insert any code.

Thanks much.

Regards,

Diana
