Trouble with date format

I’ve looked at what I can about the date format and I’m having trouble changing it per the theme I’ve purchased. Support takes days with the theme designers so I wonder if I can get some help here.

The theme has a specific layout for the home page. It’s showing the date like this: 2013-01-30 14:06:40 even with it changed to F j, Y in the WordPress admin settings.

I’ve searched for the lines on the homepage where the date shows and this is what I see

<span class="date"><?php echo $review['post_date'] ?></span>

Other than ‘orderby’ that’s the only spot where the date is in the file, and it’s right above the title (where it shows up on the page) in the code so I assume that’s the right spot. I don’t quite understand why it’s still showing the date and time. Nor do I see where to add a custom date format in this section because isn’t the custom date format in ( ) brackets like that?…and that’s not in the home page php file.

Should I be looking somewhere else? Bit of a noobie with WordPress right now.

Thanks
