Hello,
Issue with logout can appear if you use IP to access the server. It is fixed in upcoming 10.4 version.
Try to use hostname and you will see that logout works as supposed.
About customer login...
I checked your server and found that customer is in "Pending" state and you have a task in CBM Home page to approve or reject him. Also his subscription is also in "Pending" state because invoice has not been paid and hosting was not provisioned into Panel. Mark invoice as paid (you can use "Quick manual payment" tool in invoice profile) and wait for 5 minutes (system will automatically provision subscription).
As an alternative you can force provisioning - go to Events, find event ProcessPanel with needed subscription id, expand it and click "Run now".
