I've installed Viki, Semantic Titles, TitleIcons and then VikiTitleIcons, running update.php each time. Semantic Title works, TitleIcons are displaying on the pages (when set via category) and in search windows, but not within a VIKI graph. All the graph shows is the site logo for every type of node.
Not getting any errors that I can see, and Version page shows VikiTitleIcon as being installed. However, if I run the API call defined in ApiVikiTitleIcons.php, it shows that it's not bringing back any associated title icons with the page. So it looks like the install is fine but for whatever reason it's not finding the images when it queries.
Any ideas as to what could be wrong and prevent the icons being switched from the wiki logo?
