When an administrator attempts to view the profile of a member with an '@' in their username using the 'More options' button on the Organization Members tab, the administrator is signed out in the newly opened tab.

Three options:

1. Replace the '@' in the URL of the new tab with '%40' and refresh.
2. Log back in within the new tab.
3. Use the Profile button that appears when clicking on a username instead.
