I just went and visited the link you posted and yes you do get a copy of your latest post…
I also noticed, with great distress, that your site loads extremely slowly, for a site called ‘web optimist’ as an seo blog and source for systems optimization, this is a serious problem.
I have multiple suggestions for you just on the basis of the information you have provided:
1) update to the latest version of wordpress. major code changes, security fixes and code optimizations have taken place since the version you reported.
2) check your plugins for updates and latest versions as well. some older versions of plugins are known to conflict with SFP, specifically some SEO plugins remove functionality that SFP requires inorder to opperate.
3) make sure your WP-Cache does NOT cache the Forums page. although this does reduce the speed of the forums in relation to the rest of your site, it is better than having a cache of an empty forum being fed back to you over and over again, even though the forum’s content does change.
4) update to the latest version of WP. (so important it required restateing.)
5) routinely optimize your SQL database. writing and re-writing your database with wordpress often leaves stray data in the tables and sorting through it slows down SQL operations.
6) If at all possible, update your PHP … or ask your provider to do so… again many security updates and code optimizations since the version you have reported. (why on earth you have a developer’s version, I’ll never know)
7) Update to the latest version of WordPress.
