Question
Does Plesk support Drupal 9 or 10?
Answer
Drupal version 9 reached its end of life on Nov 1st, 2023 and due to this, installation for it via Plesk will remain absent, however it can still be installed manually on Plesk by using the official Drupal guides on the following link:
https://www.drupal.org/docs/user_guide/en/installation-chapter.html
Note: Support related to any manually installed Drupal 9 versions on Plesk is very limited, because these versions have not been tested extensively on Plesk servers and are not officially supported by Plesk
Alternatively, you may use and manage Drupal 9 and its newer version updates on a Plesk server by using the Softaculous Auto Installer extension for Plesk, which is available on the following link:
Softaculous Auto Installer extension
You may install Drupal 10 on a newly added domain in Plesk by following these steps:
1. Log into Plesk
2. Go to Domains > example.com > Get Started
3. Press on More Apps
4. Enter Drupal in the Application search box and press Search
5. Press on the Install button
