Problem:

The GD graphics library is not enabled/ compiled in your PHP configuration. The GD graphics library is essential for image manipulation using PHP code such as auto thumbnail creation, resize image, add copyright text and generate graphs.

Solution:

Make a request to your server administrator to enable the GD graphics library in your PHP INI.

To check whether your GD graphics library is enabled or not, use the phpinfo() function. Or if you already have the One Admin directory uploaded to your web server, you can access the URL http://your_domain.com/oneadmin/phpinfo.php with your browser. Find the word 'gd'.
