If you have managed WordPress hosting, it means that the hosting company is responsible for managing core updates and plugin updates. However, if a future update is not compatible with the current theme, customers might have to pay for theme updates or they may be included for free in order to keep the site functioning properly.

In general, hosting providers are unlikely to update your theme for you. The reasons being:
1. if it's a paid theme, the provider may not have access to it.
2. If it's a free theme, the creator may update it without any intervention from the provider.
3. If it's a custom theme, the situation is dependent on the terms of your agreement with the provider.

Most hosting providers do not include theme modifications in their services. While there may be exceptions, unless you're paying a significant amount of money per month for website management services, they are unlikely to provide theme fixes for you.

Managed WordPress hosting services are available, which can automatically update plugins and themes for you.

Different providers offer different levels of service, some updating only critical security releases while others update every release. If you decide to use this type of service, it's important to ask the provider how they handle updates. Ideally, they should take a backup before running updates, check the site for any issues (either manually or automatically), and roll back the changes if necessary.

WordPress is programmed to automatically update small changes, but not major ones. While some users appreciate automatic updates at all times, others are more cautious because an update could potentially be incompatible with their plugins or themes. There are also instances where users may not want a certain new feature, or may prefer greater control over their installation.

Users have the option to enable/disable automatic updates or configure them to only apply to minor releases/major updates by changing the wp-config.php file. For instance, if you want to enable automatic updates, simply add the following line: define('WP_AUTO_UPDATE_CORE', true);. If you want to turn off all automatic updates (including minor ones), use define( 'AUTOMATIC_UPDATER_DISABLED', true );.

If you are not comfortable using the wp-config.php file, you can manage updates by adding filters to your theme or plugin's functions.php. The Easy Update Manager plugin is another option for enabling automatic updates, but that comes with its own risks.

Despite the risks, many WordPress users prefer the automatic update method as it offers convenience and simplicity.

With managed WordPress hosting, the hosting company typically takes care of core updates and plugin updates for you. However, if a future update is not compatible with your current theme, you may need to pay for theme updates or the hosting company may include them for free to ensure your website continues to function properly. It ultimately depends on the specific terms and conditions provided by your hosting provider.

In addition to managing core and plugin updates, managed WordPress hosting often includes other benefits and services. These may include automatic backups, enhanced security measures, performance optimization, and technical support.

Automatic backups ensure that your website's data is regularly saved and can be restored in case of any issues or data loss. Enhanced security measures help protect your website from potential threats such as malware or hаcking attempts. Performance optimization focuses on optimizing the speed and performance of your website, ensuring it loads quickly and efficiently for your visitors. Technical support is also typically provided, so you can reach out to the hosting company's team if you have any questions or encounter any problems.

managed WordPress hosting often offers a user-friendly interface or control panel specifically designed for WordPress users. This makes it easier to manage your website, install plugins, and customize your theme without needing technical expertise.

Managed WordPress hosting may also include specialized caching mechanisms to help improve the speed and performance of your website. These caching systems store static versions of your website's pages, reducing the load on your server and delivering faster page load times to your visitors.

Some providers may offer specialized features like staging environments, which allow you to create a clone of your website where you can test changes or updates before making them live. This ensures that your live website remains unaffected by any potential issues or bugs during the testing phase.

Additionally, managed WordPress hosts often have server configurations optimized specifically for WordPress websites, ensuring compatibility and optimal performance. They may also offer scalability options, allowing you to easily handle increased traffic and growth by upgrading your hosting plan.

Ultimately, managed WordPress hosting is designed to simplify the management, security, and performance of your WordPress website, providing a convenient and efficient hosting solution tailored to WordPress users.
