"Index" wiki page doesn't appear on group page if it's the only page
The get_group_topics
view removes the wiki page with the slug index
from the list of wiki pages it passes into the template. Therefore, if index
is the only one in the group, the list is empty and entire block gets skipped: l227. To fix this one could change the condition in the template to
{% if wiki_pages or wiki_has_index %}
