Search box not returning any results

I have a SharePoint 2010 solution.

I've started the search service application, enabled crawling, did a full crawl, and created a Search Center Sub site. I've also set up a crawl rule. Looking at the Crawl logs, there is data that is indexed, and ready to be returned in a search result.

However, when I go to my search center subsite on my sharePoint site, and search for a term, no results come back. I've tried several key words that are on the site, but no results.

Does anyone have any suggestions why there are no results being returned in search?
