Images don't appear, items don't show up

I've installed Omeka on Dreamhost using their one-click which BTW is NOT one-click. Anyway finally got things up and running last night and went to try adding some items today. The first item added just fine but the image was blank No error message, just a blank screen. Then this evening on a different computer I've tried creating a new item and it circles awhile but never ends up loading. Suggestions???

Have you tried to enable error message display?
