Undefined array key "iid_iswitch"

[Mik J]

Hello,

I have this error in my php-fpm logs

"NOTICE: PHP message: PHP Warning: Undefined array key "iid_iswitch" in /roundcubemail/plugins/ident_switch/ident_switch.php on line 100"

I have search but have not found what it could be.

Roundcube: 1.5.3

Php: 8.0.22

Hi,

I get the same issue. To solve it, you can have a look at : https://www.roundcubeforum.net/index.php?topic=30081.0

It requires to modify the file program/lib/Roundcube/rcube_smtp.php. It is a workaround and I don’t know how to prevent this change in the Roundcube code itself.

Regards.

Roundcube 1.6.1 same problem.

My workaround for this (I know isn’t perfect or even good, but works, and don’t mess in logs anymore):

Changes in ident_switch.php at line 100:

Before:
\$iid_s = $_SESSION['iid2' . self::MY_POSTFIX];

Change to:
if (array_key_exists('iid' . self::MY_POSTFIX, $_SESSION)) { $iid_s = $_SESSION['iid' . self::MY_POSTFIX]; } else { $iid_s = -1; }

In my short tests works like a charm.

Hello. Will update my Roundcube installation and check this issue next week.

I believe, it’s a PHP 8 issue. Not related to roundcube of ident_switch version.
