PHP Fatal error at WordPress Initialization

[verenaroe]

I copied Code from my Theme to a separate Plugin.

I do this at the very beginning of my Plugin code:

// Load the WordPress library.
require_once __DIR__ . '/../../../wp-load.php';

When it's running I get the following error:

[05-Jun-2023 12:21:46 UTC] PHP Fatal error:  Uncaught Error: Class 'PR\DHL\Utils\API_Utils' not found in /app/wordpress/wp-content/plugins/dhl-for-woocommerce/includes/pr-dhl-api/class-pr-dhl-api-paket.php:22

As soon as I deactivate the plugin there's no error.

Uninstall and reinstall the newest version of the plugin didn't fixed the error. WordPress Version: 6.2.2

@verenaroe Thank you! we will check it and let you know.

I think our autoload files in the plugin are causing this and are interfering together. I will take a look at it and let you know.

Okay so the error is that wp-load is accessing your code before your autoloader is loaded. If I add this line on top of wp-load it works:

include_once( '../dhl-for-woocommerce/includes/class-pr-dhl-autoloader.php' );
require_once __DIR__ . '/../../../wp-load.php';

Now I have to find out how I can write my Plugin, so it doesn't depend on wp-load anymore. I think it's my fault then, maybe just nice to know for you I saw the same error message in the wordpress forum so I thought it's an error in the dhl plugin. https://wordpress.org/support/topic/new-version-3-4-1-created-a-fatal-error-on-our-website/
