How to Fix the ‘GD Graphic Library’ Error in XAMPP and Enhance Theme Customization

The error message you’re encountering indicates that the GD graphic library is not installed on your local XAMPP server. GD is a PHP extension commonly used for image processing tasks.

To resolve this issue, you’ll need to enable the GD extension in your PHP configuration. Here’s how you can do it:

1. Locate php.ini: Find the php.ini file in your XAMPP installation. This file contains configuration settings for PHP.
2. Enable GD extension: Look for the following line in php.ini:

   ;extension=gd

Remove the semicolon at the beginning of the line to uncomment it:

   extension=gd

3. Restart Apache: After saving the changes to php.ini, restart the Apache server in XAMPP. This will apply the changes you made to the PHP configuration.

After completing these steps, the GD library should be enabled on your XAMPP server, and you should no longer encounter the error message when changing themes.
