Pagination shows same posts

[ Moderator note: moved to Fixing WordPress. ]

Hi,

there seems to be a problem with the pagination feature? The “older posts” shows the same posts over and over again. Do you guys have an idea what’s the problem here?

The site has the newest WP-version and is in coming soon -mode, so cannot be viewed directly. We asked the developer of the theme, and they told to check WP.

Thanks in advance!
