use following command

php –ini

Check for GD in php.ini

1. Edit the PHP-FPM php.ini File: Open the main php.ini for PHP-FPM:
   sudo nano /etc/php/8.4/fpm/php.ini

2. Look for extension=gd: Use the search function (usually CTRL + W in nano) to locate any lines that mention extension=gd.
3. Comment Out Duplicate Entry: If you find extension=gd in php.ini, comment it out by adding a semicolon (;) in front of it: php.ini
   ;extension=gd

4. Save and Exit: Save the file and exit the editor.
5. Restart PHP-FPM: Restart PHP-FPM to apply the change:
   sudo service php8.4-fpm restart
