  • The Certificate dialog should open

  • Switch to the tab Details

  • Within the list, scroll down until you reach the entry Thumbprint and click on that entry

  • In a second browser window, open the EDIT WP 5.7 Certification Authority page and look for the SHA-1 fingerprint of the server you currently wanted to access

  • Compare the Thumbprint value with the value for the SHA-1 fingerprint of the current server in the EDIT WP 5.7 Certification Authority page.

Note: Proceed only, if the fingerprints are identical. Otherwise, inform the editsupport@bgbm.org EDIT Support Team immediately !

From now on, you should never be minded by an security alert for this server.

But, you will have to repeat these steps once for each other Community Single Sign-On (CSSO) enabled web sites you did not have visited before !
