I'm upgrading from Debian 12 to 13. During the upgrade, I left all the configuration files as they were.
I followed the steps in the document "Fixes you need after upgrading Debian from 12 to 13 (trixie)".
I can access emails through Roundcube, but Roundcube returns 0 for the user quota.
If, in the Dovecot configuration file, under Virtual Mail Accounts, I change the line "CONCAT('*:bytes=', mailbox.quota*1048576) AS quota_rule \" to "mailbox.quota*1048576 AS quota_storage_size \", Roundcube does display each user's quota. When a user exceeds their quota percentage, they receive a message indicating the percentage exceeded.

However, in iRedAdmin, when viewing the user list, it always shows 0% and 0 email addresses, although the quota limit is displayed correctly.
Is there a missing step in the operating system update, a step in the document, or a modification to the configuration files that hasn't been considered?
