Try each of the following until the issue is resolved:

1. Log into your website with a supervisor account and navigate to the directory search page that isn't functioning properly.
2. Edit the page, then edit the directory part
3. In the "Records to Include" section, verify that 'Organization Only' or 'Both Organizations & Individuals' is selected.
4. Verify fields from the 'Organization' section of the Profile Fields are being displayed. (i.e, organization records do not contain a first name and therefore nothing would display even if an organization was found).
