Excellent! That's a handy bit of knowledge and it worked! Thank you!

Posts that are in the same category as the slider are excluded from the home page (to remove duplicates).

Try adding a post to the "uncategorized" category and see if that loads on the home page.

I do, but it's in Maintenance mode. I've created a username/pass for you so you can see the front-end. I'll email it to you separately. Same as URL (the candidate hasn't decided and doesn't want the information out yet).

Possibly, do you have a link to your site?

I've got posts showing up in the slider just fine, but the main section that would normally show my most recent posts displays an error:

"Not Found
Sorry, but you are looking for something that isn't here."

Could a plug-in have caused this?
