1. **jQuery Conflicts**: WordPress uses its own version of jQuery, and any conflict could cause issues.
2. **Elementor Dependency Conflicts**: Elementor has its own scripts, and custom scripts might interfere with its functionality.
3. **Selectors Overwriting Elementor DOM**: The script might inadvertently target elements or IDs used by Elementor.

To debug and fix this:

### 1. **Scope the Script**
Avoid running the script globally to ensure it doesn't affect other admin pages, especially Elementor. Wrap it in a condition that checks the current admin page:

jQuery(document).ready(function($) {
    if (typeof pagenow === 'undefined' || pagenow !== 'your_custom_post_type') {
        return;
    }
    
    var fileFrame;

    $('.gallery-upload-button').on('click', function(e) {
        e.preventDefault();

        // If the media frame already exists, reopen it.
        if (fileFrame) {
            fileFrame.open();
            return;
        }

        // Create a new media frame
        fileFrame = wp.media({
            title: 'Select Images',
            button: {
                text: 'Add to Gallery'
            },
            multiple: true
        });

        // When an image is selected, run a callback.
        fileFrame.on('select', function() {
            var selection = fileFrame.state().get('selection');
            var galleryInput = $('#galerie');
            var galleryPreview = $('#gallery-preview');

            galleryInput.val(''); // Clear previous value
            galleryPreview.empty(); // Clear preview

            selection.each(function(attachment) {
                var imageId = attachment.id;
                var imageUrl = attachment.attributes.sizes.thumbnail.url;

                galleryInput.val(function(i, val) {
                    return val ? val + ',' + imageId : imageId;
                });

                galleryPreview.append('<li data-id="' + imageId + '"><img src="' + imageUrl + '" /><button type="button" class="remove-image-button">×</button></li>');
            });
        });

        // Open the media frame.
        fileFrame.open();
    });

    // Remove an image from the gallery
    $(document).on('click', '.remove-image-button', function() {
        var imageItem = $(this).closest('li');
        var imageId = imageItem.data('id');
        var galleryInput = $('#galerie');

        imageItem.remove();

        var ids = galleryInput.val().split(',');
        galleryInput.val(ids.filter(id => id != imageId).join(','));
    });
});

Replace `your_custom_post_type` with the actual slug or identifier for the admin page where this script should run. If it's a specific settings page, use the appropriate check.

### 2. **Enqueue Scripts Correctly**
Ensure the script is enqueued only where necessary. Use `wp_enqueue_script` in your `functions.php`:

function enqueue_custom_gallery_script($hook) {
    // Only enqueue script for a specific admin page.
    if ($hook !== 'post.php' && $hook !== 'post-new.php') {
        return;
    }

    wp_enqueue_script(
        'custom-gallery-script',
        get_template_directory_uri() . '/js/custom-gallery.js', // Adjust path
        ['jquery', 'wp-media'], 
        null, 
        true
    );
}
add_action('admin_enqueue_scripts', 'enqueue_custom_gallery_script');

—

### 3. **Test with Elementor**
– **Disable the script temporarily**: Remove the script and verify if Elementor works. This ensures the script is the source of the issue.
– **Test Scoping**: After scoping, check if the Elementor backend starts working again.

—

### 4. **Browser Console Logs**
Open the browser's developer console and check for JavaScript errors when Elementor's backend fails. If the custom script triggers any errors, they will guide you toward specific conflicts.

### 5. **Script Dependency**
Ensure that the `wp.media` library is properly loaded and not overridden. Add `wp-media` as a dependency in the `wp_enqueue_script` function.

### 6. **Alternative Approach**
If the issue persists, consider dynamically loading the script only when required, using AJAX for gallery interactions to avoid any direct DOM manipulation that might conflict with Elementor.

Let me know how it goes!

// Check if on the edit screen for the correct post type
if (!isset($post) || $post->post_type !== 'projekte') { // Replace 'custom_post_type' with your post type slug
return;
}

// Enqueue WordPress Media Library
wp_enqueue_media();

// Enqueue custom JavaScript for the meta box
wp_enqueue_script(
'gallery-meta-box-script',
get_stylesheet_directory_uri() . '/js/gallery-meta-box.js', // Update the path as needed
['jquery'], // Dependencies
time(), // Version (null to disable versioning)
true // Load in footer
);
wp_enqueue_style(
'gallery-meta-box-style',
get_stylesheet_directory_uri() . '/admincss/gallery-meta-box.css', // Update the path as needed
[],
null // Version
);

}

add_action('admin_enqueue_scripts', 'enqueue_gallery_meta_box_scripts');

—

### 1. **Scope the Script Properly**
Currently, the script is scoped to the `projekte` custom post type edit screen, which is good. However, ensure the `$post` variable is always set by including a check for the admin screen and avoiding unintended cases:

function enqueue_gallery_meta_box_scripts($hook) {
    // Ensure we are in the admin and on the edit screen for the correct post type
    if (!in_array($hook, ['post.php', 'post-new.php'])) {
        return;
    }

    global $post;
    if (!isset($post) || $post->post_type !== 'projekte') { // Replace 'projekte' with your custom post type slug
        return;
    }

    // Enqueue WordPress Media Library
    wp_enqueue_media();

    // Enqueue custom JavaScript for the meta box
    wp_enqueue_script(
        'gallery-meta-box-script',
        get_stylesheet_directory_uri() . '/js/gallery-meta-box.js', // Update the path as needed
        ['jquery'], // Dependencies
        time(), // Version (use time for development; change to versioned file for production)
        true // Load in footer
    );

    // Enqueue custom CSS for the meta box
    wp_enqueue_style(
        'gallery-meta-box-style',
        get_stylesheet_directory_uri() . '/admincss/gallery-meta-box.css', // Update the path as needed
        [],
        null // Version (use null for no versioning, or a specific version string)
    );
}
add_action('admin_enqueue_scripts', 'enqueue_gallery_meta_box_scripts');

—

### 2. **Versioning**
Using `time()` for versioning is fine during development, but in production, this can lead to caching issues. Update it to a static version number or use `filemtime` for versioning based on file modification time:

$version = filemtime(get_stylesheet_directory() . '/js/gallery-meta-box.js');

Then use `$version` for `wp_enqueue_script` and `wp_enqueue_style` calls.

—

### 3. **Check Elementor Compatibility**
To prevent conflicts with Elementor, ensure your script is not loaded on Elementor's backend:

if (defined('ELEMENTOR_VERSION') && ElementorPlugin::$instance->editor->is_edit_mode()) {
    return; // Do not enqueue on Elementor editor pages
}

Add this condition inside your `enqueue_gallery_meta_box_scripts` function.

—

### 4. **Load Dependencies**
You're already loading `wp_enqueue_media`, but if the script heavily depends on WordPress's media uploader, explicitly add `wp-media` as a dependency:

wp_enqueue_script(
    'gallery-meta-box-script',
    get_stylesheet_directory_uri() . '/js/gallery-meta-box.js',
    ['jquery', 'wp-media'], // Dependencies
    time(),
    true
);

—

### 5. **Debug Elementor Backend**
– Temporarily comment out the `wp_enqueue_script` and `wp_enqueue_style` lines and test the Elementor backend editor. If it works after commenting out your script, it confirms a conflict.
– Use the browser's developer tools console to check for JavaScript errors or conflicts.

—

### 6. **Test in Isolation**
Ensure your `gallery-meta-box.js` and `gallery-meta-box.css` files are not applying styles or scripts globally. For example:
– Add unique selectors or scoped classes for any DOM manipulation or styles.
– Avoid targeting common classes or IDs that might overlap with Elementor or other plugins.

—

### 7. **Enable Script Debugging**
Enable WordPress script debugging by adding this line to your `wp-config.php`:

define('SCRIPT_DEBUG', true);

This forces WordPress to load non-minified versions of its scripts, which can help identify conflicts.
