One or more recommended modules are missing… When you see this message in your site diagnosis, it usually means that the “imagick” module is missing or, more accurately, not being used by the server in 99% of WordPress websites.
Is it a big issue if the imagick module is missing?
No, in most cases, your server has an alternative (the GD module) for image manipulation and editing.
What does the imagick module do?
The imagick module allows for image manipulation, such as scaling, cropping, and resizing of images.
How can I make sure that the GD module is present on my website and replaces imagick?
How can I be certain that the absence of the imagick module doesn’t cause any issues?
Upload an image in WordPress and try editing it. If you can successfully make changes and save the file, it means that the alternative GD module is functioning properly. You can then ignore the notification about the missing imagick module.
