If your WorldShare URL looks like this https://<your WorldShare instance name>worldcat.org/wms/cmnd/. You are not seeing a module because that URL does not point to a specific module. For example, to go directly to the Interlibrary Loan tab, you'd add "nd/" to the end of the URL. Without it, WorldShare will appear with the logo, but no buttons or tools will appear. Here's a list of the modules with their codes:
WorldShare Acquisitions = acq/
WorldShare Analytics = analytics/
WorldShare Circulation = circ/
WorldShare ILL = nd/
WorldShare License Manager = lman/
WorldShare Metadata = metadata/
