OpenPDC Archive not archiving data

Hello Stephen
Suddenly OpenPDC archive stopped archiving .For last 10 hours no archiving d file.But OpenPDC is running and collecting data from PMUs.Can you please tell me where to check the problem.Thank you.

Your first troubleshooting step should be to check the openPDC Console and ErrorLog.txt. While you are checking the console, initialize the historian to see if it raises any errors.
