Plesk Obsidian
Check the PHP Imagick extension before trying to install anything
On managed shared hosting you should not run root package commands. Plesk PHP normally provides Imagick, but the enabled modules can differ by PHP version and service configuration.
ImageMagick and Imagick are related but different
ImageMagick
The server software and command-line tools that process images.
Imagick
The PHP extension that lets WordPress and other PHP applications use ImageMagick.
Check your website
- 1Open Plesk
Choose Websites and Domains, then PHP Settings for the affected domain.
- 2Confirm the PHP version
The command line and website can use different PHP versions, so check the website setting.
- 3Inspect PHP information
Look for an Imagick section or let the application report its detected image library.
If Imagick is not available
Open a support ticket with the domain, selected PHP version, application and the exact feature that needs Imagick. UKC can check the appropriate managed-server configuration.
WordPress checks
Site Health
WordPress Site Health can show which image editor is active and whether recommended modules are missing.
Plugin requirements
Confirm that the plugin really needs Imagick and supports the PHP version selected for the site.
For the Plesk platform procedure, see the official ImageMagick module guidance.
Next step
Ask UKC to check the hosting account
Include the domain, PHP version and exact application error, but no passwords.
