have a blog running on the front page of my site. When I click the link on the bottom that says next, I can navigate to previous posts. [home/page-1] Then I scroll down and click next again and come to [home/page-2]

This all works fine until I scroll to the bottom of [home/page-2] and click next for the third time. This time it returns me to [home/page-2].

Could someone tell me how to fix this bug?

Hi,
Try manually setting the number of items on one page in JoomSEF -> Manage Extensions -> Content (or other component you use for blog) -> Common tab using the "Items per page" option.
