Compatibility issue with Spectra Pro and temporary fix

[Bokis]

"Load more" in Global Media tab doesn't work if Spectra Pro is activated with PHP >8.
This is actually a Spectra problem, but here is a fix you can try if you get "Fatal error" after clicking on "Load more".

Create the file /wp-content/mu-plugins/fix-spectra-global-media.php and add following:

<?php
/**
 * Plugin Name: Fix Spectra Pro + Global Media AJAX Fatal
 * Description: Prevents Spectra Pro from crashing media AJAX when attachment path is empty.
 * Author: Internal
 */

add_action('plugins_loaded', function () {

    // Only run in admin
    if (!is_admin()) {
        return;
    }

    global $wp_filter;

    // Check if Spectra filter exists
    if (isset($wp_filter['wp_prepare_attachment_for_js'])) {

        foreach ($wp_filter['wp_prepare_attachment_for_js']->callbacks as $priority => $callbacks) {

            foreach ($callbacks as $callback_id => $callback_data) {

                if (
                    isset($callback_data['function']) &&
                    is_array($callback_data['function']) &&
                    is_object($callback_data['function'][0]) &&
                    get_class($callback_data['function'][0]) === 'SpectraPro\Core\Admin'
                ) {

                    $original_callback = $callback_data['function'];

                    // Remove original Spectra filter
                    remove_filter(
                        'wp_prepare_attachment_for_js',
                        $original_callback,
                        $priority
                    );

                    // Add safe wrapper
                    add_filter(
                        'wp_prepare_attachment_for_js',
                        function ($response, $attachment, $meta) use ($original_callback) {

                            try {
                                return call_user_func(
                                    $original_callback,
                                    $response,
                                    $attachment,
                                    $meta
                                );
                            } catch (ValueError $e) {
                                // Fail silently and return original response
                                return $response;
                            }

                        },
                        $priority,
                        3
                    );
                }
            }
        }
    }

}, 100);

What this does:

• Locates Spectra Pro’s filter on wp_prepare_attachment_for_js
• Removes it
• Re-adds it inside a try/catch wrapper
• Catches the ValueError thrown by file_get_contents('')
• Returns a normal media response instead of a 500 error
