I've installed Geommunity/CB in a separate module, published it, included it in a new article with {loadposition} and created a menu link to the article.
Throughout my site I have the CB Online module on the left. All other pages show who's online, but the Geommunity module article blanks out the user text.

Who's Online on left menu shows Test User.
Go to Member Map from main menu.
Who's Online has a bullet but no text for user.
View Source shows the <a href> link to the user profile, but no text in the link.
I made a copy of Geommunity, published it to my normally empty footer on all pages, and on all pages the CB Online module had empty user text.
It also occurs when I change to other templates.
I think this is probably a Geommunity issue, and I'm already working with the developer. Thought I'd cross post here in case anybody was aware of or wanted to dig into the problem.
