I am new to WordPress web development and my auto updates option is not being enabled despite trying many methods that I was guided by Hostinger support service.

1. I have disabled all plugins to check if issue resolved, did not work.

2. I have switched to default theme, did not work.

3. I have reinstalled wordpress version, did not work.

4. I have added these 2 lines in wpconfig.php:

   define( 'WP_AUTO_UPDATE_CORE', 'true' );
   define('AUTOMATIC_UPDATER_DISABLED', false);
   

   There are no conflicting lines of code, did not work.

5. I had also manually added auto update lines for theme and plugin in theme file editor php file. What I recall, these were the 2 lines that I added:

   add_filter('auto_update_theme', '__return_true');
   add_filter('auto_update_plugin', '__return_true');
   

   Still didn't work.

At the moment, there are some scheduling actions that have failed, but I am not sure how to proceed further to resolve my issue. Kindly guide me with detailed steps as to how to resolve issues as I am new to worpress web development.
