NEXT POST BUTTON

Hi there,

Any chance you can link us to the site in question?

You can use the private information field.

Let me know :)

Try this CSS:

.post-navigation .nav-previous {
    display: none;
}

I try to explain better: i have now pagination NEXT for only nextpage. thats ok and not the topic.
Want i want is to add a nextpost NEXT button. and it should go back in time not to newest posts

In that case it's probably easier to create your own custom post navigation using a block element:
