How do I eliminate duplicates from showing up in the Post Pages ? BTW, I have Atahualpa Version: 3.7.13.

without a bit more information I could only say 'undo what ever you did to cause it.'

It is a new install and the dups started from the beginning. Do you offer theme modifications ?

Duplicates of what? Do you have a URL pointing to an example?

You need to give mee an exact example of where to look for a duplicate. Looking at the site quickly, I don't see a duplicate, but I don't know what I would be looking for.

Ok, click here. You will see many dups and then click on any one of the images. more dups.

How are those posts being created. If you only put one post per item only one should show. If they are being generated from other feed via a plugin or code then those feed could each have the same posts. If it is the latter search engines may penalize you for those.

Yes they are being generated by a feed. But is there a way to eliminate them inside of this theme ? BTW, I am using these same feeds with another theme and have no problems with duplicates.

Without digging into the other theme, your site, the plugin and the feeds, there is no way to know off hand, sorry.
