Hi RC forum members
,
We recently upgraded from RC 1.5.2 to 1.6.0, Everything seems to be running OK except for some PHP warnings being thrown into error.log file
PHP Warning: Undefined array key 2 in /usr/share/roundcubemail/program/include/rcmail_attachment_handler.php on line 64
PHP Warning: Undefined array key "" in /usr/share/roundcubemail/program/lib/Roundcube/rcube_imap.php on line 1045

I have traced the particular lines for some of these an have implemented some extra logic check on array keys, though not sure if this makes things worse. Does any one know why this is happening?, I did not see these errors under 1.5.2. The last 6 in that list seem to be occurring the most. We are running RC 1.6.0 with Caddy 2.6.2 and PHP 8.0.26 inside a docker container.
