I'm having a problem with the new DiRT plugin. Here is what is happening:

I added the DiRT Directory client to NYCDH, a multisite install running CBOX

I network activated the plugin

once network activated, I saw "Digital Research Tools" in the sidebar of a group

I clicked on it and saw a link to "Explore more tools from DiRT on the Digital Tools Directory." The link went here - http://nycdh.org/tool/

When I clicked on the link, I hit a blank page
