Blogging problems!!!

I just realized this afternoon that for some reason, the files for individual posts are not being posted to my site. The links on the right send you to an address on my site, but...nothing is there. I've tried fiddling with the settings, but so far I haven't been able to fix the problem. I've adjusted the blog's settings so that all of the posts show up on the main page, and I'll continue to play with the other settings. My apologies - hopefully I'll get it fixed soon!!!
