Hello,
We apologize for the issue you are facing with your website. The warning message you are seeing, "Undefined array key ‘versions’", typically indicates that there is an issue with how the plugin is trying to access an array element that does not exist.
To resolve this issue, you can try the following steps:
- Update Rank Math: Ensure that you are using the latest version of the Rank Math plugin. Updates often include bug fixes that may resolve such warnings.
- Check for Plugin Conflicts: Sometimes, other plugins can conflict with Rank Math. You can temporarily deactivate other plugins to see if the warning disappears.
- Review PHP Version: Make sure your server is running a supported version of PHP. You can check this by navigating to Tools → Site Health → Info in your WordPress dashboard and looking under the Server section for the PHP version.


- Contact Hosting Provider: If the PHP version is outdated, you may need to contact your hosting provider to upgrade it.
If these steps do not resolve the issue, please reply to this ticket with your website URL so that a human agent from our support team can assist you further. Thank you for raising this concern!
