I posed the topic, "
WPLMS4 Login Problem" and it was closed. However, I found the real problem behind this problem which has nothing to do with plugin versions nor the WPLMS theme version issue.
I confirmed the synchronization between WP Login and VibeBP Login is broken when multiple users have a plus sign ("+") in their email address like "
[email protected]," and they share the same mailing destination addressed, "
[email protected]."
For example, if there are two users like below, the sync won't happen for testuser002 so that you need to go through VibeBP login manually.
(1) The first user
ID: testuser001
eMail:
[email protected]
(2) The second user
ID: testuser002
eMail:
[email protected]
Please confirm if my finding is true. If it is true, I think it is a bug that needs to be fixed.
