The error you're encountering indicates that the class `ElementorCoreSchemesColor` cannot be found, which is likely due to a compatibility issue between the WPML plugin and the version of Elementor you are using. Here are some steps you can take to resolve this issue:

1. **Update Plugins and Themes**: Ensure that all your plugins (including WPML) and your theme are updated to their latest versions. Compatibility issues often arise from using outdated versions.

2. **Check Compatibility**: Verify that the version of WPML you are using is compatible with the version of Elementor installed. Sometimes newer versions of Elementor may deprecate certain classes or methods that WPML relies on.

3. **Rollback Elementor**: If updating doesn't help, consider rolling back to an earlier version of Elementor that is known to work with your version of WPML. You can use the WP Rollback plugin to easily switch between plugin versions.

4. **Debugging**: If you have debugging enabled, check for additional errors or notices in your logs that may provide more context about the issue.

5. **Contact Support**: If the problem persists after trying the above steps, you may want to reach out to WPML support for assistance. They may have specific recommendations or fixes for compatibility issues with Elementor.

6. **Manual Fix**: If you're comfortable with code, you could also investigate the `WidgetAdaptor.php` file mentioned in the error message. Look for the line that references `ElementorCoreSchemesColor` and determine if it can be replaced with a different class or if additional checks need to be added to prevent the error.

By following these steps, you should be able to identify and resolve the issue with the missing class.
