Error on uploading an image


"PHP Fileinfo extension must be installed

Reason "PHP Fileinfo extension must be installed/enabled to use Intervention Image."

The project needs the fileinfo extension.


As you can see on the image, it can be enabled from PHP Selector. But if there is no PHP Selector you should have access to WHM.


Initially, we login to WHM and navigate as follows,

Software >> EasyApache 4 >> Customize >> PHP extensions.

Here we search for fileinfo and enable phpx.x-php-fileinfo for all versions. Finally, we click on Review and Provision.

This enables the file extension for all the PHP websites in the server.

Let me know about this.
