I have since reverted back to j1.5.23, and have same problem. I have a seperate topic open for it...I got no response here for several days.
Mass email works from joomla and cb. There is no email verification link sent when either cb or cbsus is configured for verification before or after payment, and this is true with pay offline, or paypal. Once payment is made, I do get a welcome email. There is also a thank you for registering e-mail that comes out when a new person registers, but there is no email verification link. It does say where the message was sent from, but no "click here" type line one might use to confirm their email, and it will not allow a user in, unless the system is reconfigured for email verify to off. I have tried turning off and on both in cb and cbsubs multiple times. I never get any link to verify my e-mail. If I have email verification on, they get no link, and can not log-in. All they get is a message on the site that says to check their email for instructions.
