Updating to version. 2.8.7 and 2.8.8, issue!

Hi Support.

Cannot edit profiles, using the edit button on the members page, after updating to version. 2.8.7 and 2.8.8.

When clicked, it redirects to: https://my-website/username/?profile tab=main

When I rollback to version: 2.8.6, then the edit button works again and redirects to: https://my-website/user/name/?um_action=edit

Please help, thank you.
Best regards…
