The APS Catalog has been deprecated and removed from all Plesk Obsidian versions. Applications already installed from the APS Catalog will continue working. However, Plesk will no longer provide support for APS applications.
Please be aware: with the Plesk Obsidian 18.0.78 release, the support for the ngx_pagespeed.so module will be deprecated and removed from the sw-nginx package.
Plesk 18.0.47 is very outdated and it was removed from download site, so that's why you cannot manage components. You can either remove unneeded packages via yum (less desired), or first update to latest version (18.0.64 at the time of writing), and then manage components via Plesk installer
If that doesn't work, please run yum list installed | grep php to check the installed packages. Still, as mentioned by @mizar it is best to consider an update to the current version rather than manually removing components.
