I Have this exact Problem but turning on the extensions does not help. The extensions are actually all activated but the Installer doesnt recognize them.
I tried switching them on and off but that didnt help either. The Installer still doesnt recognize that there there. This is with a Joomla Update.
Hello Swen Andrew
Please, let me know the OS and Plesk version you're using so that we could try it on a test instance.
Plesk Obsidian Version 18.0.27 (Problem persisted in earlier versions as well)
Ubuntu 18.04.4
PHP 7.3.17
I was able to resolve the issue by switching the site back to PHP 7.2 and then switching back to PHP 7.3

Thank you for the provided info.
During the version switch, domain PHP configuration was regenerated.
However, the reason why this happened previously is unclear and an investigation is required.
