The situation happens when there is an approved tag wiki, but no approved tag excerpt.
Here you can see it on the tag packaging:
It seems the message "tag has no wiki summary" is subordinated at the tag wiki excerpt existence.
Also, when clicking the "learn more button" the following message appears:
There is no tag wiki for this tag … yet!...
This is not true either.
- When there is not a tag wiki excerpt, replace "tag has no wiki summary" for "tag has no wiki excerpt".
- Whenever the tag wiki exists (the detailed one), enable the "learn more" button to direct the page to the tag wiki content.
