Problem Description :
When a user send QuickLinks or email from eB web, they get error when clicking the link - "Change the Active Community"
Problem Solution :
1) a) Go to eB director > system admin> system defaults > General
b) In eB browser URL, make sure that URL set to like https://address.bentley.com/eB/Framework/default.aspx because if just use https://address.bentley.com , it just open start page
2) In IIS manager, set Default Document under default web site as shown below screenshot
