2 Dates within posts

When I make a new post the date it was created is fine, but as soon as the next day comes, there are 2 dates showing. This only happened when the theme was updated from 1.3 to 1.4. If you click on the link below you will see, but also look at the other posts the next day and see the date change to 2 dates again. I have tried to modify the templates-tags.php within the inc folder in the parent theme, but nothing seemed to change.

Oh, just one addition, if I just click on the blogs nav, its fine… it is just when you click to view the post, it shows up 2 dates.

I’m trying to work on a fix, but if you manage to do this first, please update.

I’ll add the fix as soon as I find the culprit. I’m not ruling out database issues!
