PHP Error

Hello,

We apologize for the issue you are facing with the PHP error. The warning you are seeing, "Attempt to read property ‘name’ on null," typically indicates that the code is trying to access a property of an object that is not instantiated or is null. This can happen due to various reasons, such as a plugin conflict or an issue with the theme.

To troubleshoot this issue, we recommend the following steps:

1. Update Plugins and Themes: Ensure that all your plugins and themes are updated to their latest versions. Sometimes, compatibility issues arise from outdated software.
2. Check for Plugin Conflicts: Deactivate all plugins except Rank Math and see if the error persists. If it resolves, reactivate the plugins one by one to identify which one is causing the conflict.
3. Review Your Theme: Switch to a default WordPress theme (like Twenty Twenty-One) to see if the issue is related to your current theme.
4. Debugging: Enable debugging in WordPress by adding the following lines to your wp-config.php file:

   define('WP_DEBUG', true);
   define('WP_DEBUG_LOG', true);
   define('WP_DEBUG_DISPLAY', false);

   This will log errors to a debug.log file in the wp-content directory, which may provide more insight into the issue.

If you continue to experience this error after trying these steps, please reply to this ticket with your site URL so that we can assist you further. Thank you for raising this concern!

Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
