Solved Unable to access older posts

I have no problem with Recent Topics.
I have limited to 40 the most recent topics appearing on the first page of each category. Therefore, the latest 40 topics are properly listed in each category.
The problem is that older posts are not accessible because the links to pages 2, 3, 4, 5... etc., does not appear at the bottom as  in the previous version.
I have not been able to find the way to configure so that links to the following pages containing older posts appear at the bottom (or somewhere else) on the first page.

Have a look in the Kunena Dashboard at Categories. Open a category and look in the Category Settings tab at Category Channels: if "Show this category" is selected.
In the "Display settings" tab, check if "Show this category" and "Show subcategories" are set to "Up to subcategory level".
If this helps, you need to adjust all categories.

Gindi, Both "Display This Category" and "Display Sub-Categories" had already been set up to Sub-Category Level in all Categories.

I have thousands of posts in five categories. When one of the categories is open, I only see a list of the latest 40 posts (that is the limit per page).
The question is: How to configure Kunena to show a list linking to pages 2, 3, 4, 5 ... containing older posts?

Go to the configuration (Frontend tab) and test it with a low number e.g. 3 or 4 Topics Per Page. Then you can see if the pagination generally works. If this is ok, choose again the desired number of topics and go to Kunena -> Tools and recount the statistics.

Thank you, Rich!  But it didn't work either. Reduced the limit per page to 5 and just 5 posts appeared, but no subsequent pagination.

I am using a new version 6.1.2. Probably is a glitch of this new version, because I have been looking around all over the WEB and found no recent references to pagination issues.

Maybe the pagination is there and is not displayed due to a CSS conflict. Please create a Configuration Report
