I'm working on a new blog and noticed that the article content of the first post was missing. I could see the teaser on the front page, but the actual post was empty.
Through process of elimination, I determined that it was caused by SEO Smart Links. Since it only caused a problem with the one post, I added the the first post slug to "Ignore Posts and Pages" and that corrected the problem.
If it helps any, I only added SEO Smart Links after I already had four posts up.
I had also added SEO Smart Links to an older blog still running WP 2.9.2 and it does not appear to have the same problem.
I'll live with it, because this is a great time saver, but I figured I would mention it in case someone else runs into the same thing.
