“Not Found” error

Hello,

I installed the plugin. The chat search works, whereas it asks me to search for a user and a list of links arrives when I do. When I click on one of the links with the user’s name, there is an error page saying “Not Found:It looks like nothing was found at this location. Maybe try a search?
Search for:”

This looks like a page-not-found error to me, so probably the link is bad. The link comes up as “mydomain.com/#”

What do I do to fix this?

Thanks
