Understanding the Error

The error happens when your code tries to instantiate or access the Schemes_Manager class before Elementor has fully loaded. This often occurs if your code is inside a custom plugin or theme functions file that runs too early in WordPress’s execution order.

Step-by-Step Fix

1. Ensure Elementor is Installed and Activated

The first thing to check is whether Elementor is properly installed and activated.

• Go to WordPress Dashboard > Plugins > Installed Plugins.
• Make sure Elementor (and Elementor Pro, if required) is activated.

If Elementor is missing, install it from the WordPress plugin repository.

2. Use the Correct Elementor API

Instead of manually creating an instance of Schemes_Manager, you should use Elementor’s global plugin instance:

Replace This Code:

$schemes_manager = new Schemes_Manager();

With This:

$schemes_manager = \Elementor\Plugin::$instance->schemes_manager;

This ensures you’re accessing Elementor’s internal manager correctly.

3. Delay Execution Until Elementor is Loaded

Since Elementor is not available immediately when WordPress loads, your code should run only after Elementor is fully initialized.

add_action('elementor/loaded', function() {
    $schemes_manager = \Elementor\Plugin::$instance->schemes_manager;

    if ($schemes_manager) {
        $scheme_obj_typo = $schemes_manager->get_scheme('typography');
        if ($scheme_obj_typo) {
            $scheme_obj_typo->save_scheme($theme_fonts);
        }

        $scheme_obj_color = $schemes_manager->get_scheme('color');
        if ($scheme_obj_color) {
            $scheme_obj_color->save_scheme($theme_colors);
        }
    } else {
        error_log('Schemes Manager is not available.');
    }
});

This ensures Elementor is fully loaded before accessing schemes.

4. Define $theme_fonts and $theme_colors Before Using Them

If $theme_fonts and $theme_colors are undefined, save_scheme() might cause an error.

Fix: Initialize the Variables Before Using Them

$theme_fonts = $theme_fonts ?? [];
$theme_colors = $theme_colors ?? [];

Or manually define them:

$theme_fonts = [
    'primary_font' => 'Arial',
    'secondary_font' => 'Helvetica'
];

$theme_colors = [
    'primary_color' => '#ff0000',
    'secondary_color' => '#00ff00'
];

This prevents undefined variable errors.

5. Manually Load Elementor Core (If Necessary)

If Elementor is installed but the class is still missing, try manually including Elementor’s core files before accessing Schemes_Manager.

Solution:

if (!class_exists('Elementor\Plugin')) {
    require_once ABSPATH . 'wp-content/plugins/elementor/includes/plugin.php';
}

This ensures Elementor’s plugin files are available before your code executes.

6. Debug by Checking the Available Classes

If the error persists, you can check whether Elementor\Core\Schemes\Manager exists in the declared classes.

Solution: Log the Available Classes

error_log(print_r(get_declared_classes(), true));

Then, check wp-content/debug.log to see if Elementor\Core\Schemes\Manager is listed.

Final Checklist to Fix the Error

• Ensure Elementor is installed and activated
• Use \Elementor\Plugin::$instance->schemes_manager instead of new Schemes_Manager()
• Wrap the code inside the elementor/loaded hook
• Define $theme_fonts and $theme_colors properly
• Manually include Elementor’s core if necessary
• Log available classes to debug further
• Clear cache and test again

Conclusion

The Elementor Schemes Manager Error – “Class Elementor\Core\Schemes\Manager Not Found” error usually happens when Elementor is either not loaded yet or its API is being accessed incorrectly. By following the solutions outlined above, you can prevent this error and ensure smooth execution of your Elementor customization code.

Additionally, always make sure to keep your WordPress, Elementor, and custom plugins updated to their latest versions, as outdated files can sometimes cause compatibility issues. If you are using a child theme or custom plugin, verify that there are no conflicts with other plugins by deactivating them temporarily and testing your code.

If the problem persists despite trying all these solutions, consider checking Elementor’s documentation or reaching out to their support forums for further assistance. Debug logs can provide valuable insights into what’s happening behind the scenes, so make sure to enable logging in wp-config.php if needed.
