[STR07]

I get the following warnings when using Roudcube 1.5.2 and the plugin: twofactor_gauthenticator_login along with PHP 8.0.14.

[02-Jan-2022 20:51:58 Europe/Berlin] PHP Warning: Undefined array key "twofactor_gauthenticator" in /var/www/html/webmail/plugins/twofactor_gauthenticator/twofactor_gauthenticator.php on line 416

These warnings occur after a login takes place.

Thank you very much in advance.

Ps: We are currently using version 2.0.0 of twofactor_gauthenticator_login

We fixed this by using the code from the pull request 'Fixed PHP warnings and not working config options #157'

Furthermore if you also get the following error: [05-Jan-2022 14:12:24 Europe/Berlin] PHP Warning: Undefined array key "HTTP_X_FORWARDED_FOR" in /var/www/html/webmail/plugins/twofactor_gauthenticator/twofactor_gauthenticator.php on line 536

You can fix this by changing the statement: "$_SERVER['HTTP_X_FORWARDED_FOR']" to "getenv('HTTP_X_FORWARDED_FOR')"
