On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

    The above command delivers and error that /opt/psa/var/modules/composer/composer.phar is not found.

    The correct command on CentOS 7.9 is:
    /opt/plesk/php/7.4/bin/php /usr/local/psa/var/modules/composer/composer.phar self-update --2
