Are you using templates or non-templates? If templates, make sure you have this code in your category.html template file:
Code:
<!-- Next/Previous links if spanning pages. -->
<p align=center>
<%if prev%>
<small><a href="<%prev%>">Prev <%build_links_per_page%></a></small>
<%endif%>
<%if next%>
<small><a href="<%next%>">Next <%build_links_per_page%></a></small>
<%endif%>
</p>
If you are not using templates, make sure that the following code is correct in sub site_html_category of site_html.pl:
Code:
if ($prev or $next) { $output .= qq~<p>~; }
if ($prev) { $output .= qq~<strong><a href="$prev">Prev $build_links_per_page</a></strong> ~; }
if ($next) { $output .= qq~<strong><a href="$next">Next $build_links_per_page</a></strong> ~; }
if ($prev or $next) { $output .= qq~</p>~; }
I hope this helps.
