issue when updating to Version 1.2.3.4

My hosting support insisted on the theory that when I updated from version 1.2.3.2 to 1.2.3.4 Gmail SMTP plugin inserted a line of code in the wp-config file as follows:

/** HTTPS */
define('FORCE_SSL_ADMIN', true);

This then results in a duplicated code in the wp-config file, resulting in an error message visible on the front and back end of the site.

They said:

Here the error was:

Update failed: ( ! ) Warning: Constant FORCE_SSL_ADMIN already defined in /home/xxxxxxx.cloudwaysapps.com/xxxxxxx/public_html/xx/wp-config.php on line 73 Call Stack #TimeMemoryFunctionLocation 10.0010382784{main}( ).../admin-ajax.php:0 20.0010383344require_once( '/home/xxxxxxx.cloudwaysapps.com/xxxxxxx/public_html/xx/wp-load.php ).../admin-ajax.php:22 30.0011384168require_once( '/home/xxxxxxx.cloudwaysapps.com/xxxxxxx/public_html/im/wp-config.php ).../wp-load.php:50 40.0011384576define( $constant_name = 'FORCE_SSL_ADMIN', $value = TRUE ).../wp-config.php:73 {"success":true,"data":{"update":"plugin","slug":"gmail-smtp","oldVersion":"Version 1.2.3.2","newVersion":"Version 1.2.3.4","plugin":"gmail-smtp\/main.php","pluginName":"Gmail SMTP"}}

From the above error, it is clear that, GMAIL-SMTP plugin was trying to define this constant. Kindly review this with your developer.

I will be grateful if you enlighten me.

Thanks
