What to do when Switchboard only displays a blank page

This article provides steps to address an issue where the the Switchboard loads as a blank page for one or more users. Other /admin and /main Web Interfaces will perform as expected, but the Switchboard does not.

This issue is uncommon, but when it does happen, it typically presents immediately after a Switchvox Update to a new software version. In these scenarios, the underlying cause is a contact update routine that has not fully completed yet, and will normally resolve itself within an hour following the update's completion. If that time has passed, perform a System Reboot. In the event that the issue still occurs, please perform the following steps. 

1. Log into the /admin interface

2. Go to Tools > External Contacts 

3. Click on Import External Contact Sheet. 

4. If you don't have an external contact upload, Go to Step 6

5. Backup the contact file and then Delete it from the PBX. (most likely this file is corrupted and you need to review it manually)

6. Create a new external contact file using the dummy.csv example below

7. Upload the dummy contact file

8. Delete the dummy contact file

9. Wait approximately 5 minutes for the contact files to be generated by the system

10. Reboot the PBX

11. Confirm that the Switchboard is now working as expected
