Was that a custom upgrade?
Or an install, other than the Plesk Extension? PHP Composer
^^ That is still Version 1.1.2 which is the last relevant entry in the Plesk change log: Change Log for Plesk Obsidian
No, Plesk 18.0.35 - Actually on some server, I always downgrade to 1.x. It keeps getting upgrade to 2.0x with every Plesk update. I haven't looked into how to prevent this composer auto upgrade.
Sorry @WebHostingAce Had misread the previous posts You were correct with your initial & subsequent post(s).
Was thinking Plesk PHP Composer Extension, not Composer Composer itself
Possibile there is no way to have composer 2? Plesk is still provide a composer version deprecated.
No way to ask to the Plesk team to upgrade composer?
Me too upgrade by SSH and all times need upgrade again because the obsolete 1.115 is restored.
