Package: roundcube-plugins-extra Version: 1.4.10+1-4 I got an error like this, trying to set a message Flag:
[05-Apr-2024 15:16:54 UTC] PHP Warning: Undefined property: rcmail::$imap in /usr/share/roundcube/plugins/thunderbird_labels/thunderbird_labels.php on line 318 [05-Apr-2024 15:16:54 UTC] PHP Fatal error: Uncaught TypeError: array_merge(): Argument #1 must be of type array, null given in /usr/share/roundcube/plugins/thunderbird_labels/thunderbird_labels.php:327 I think the issue is in function set_flags, around line 318 is a definition '$imap = $this->rc->imap;'. The object $this->rc->imap seems to be renamed to $this->rc->storage. Changing this one line fixed the issue for me. The same issue can be found in keyboard_shortcuts. Replacing '$rcmail->imap' with '$rcmail->storage' between lines 104 and 109 fixes the issue there.
