Hello,
We apologize for the issue you are facing with the Rank Math plugin update. To resolve the update failure, you can try the following steps:
-
Reconnect Your Website with Rank Math: Sometimes, simply reconnecting your website can fix the update issue. Go to WordPress Dashboard → Rank Math SEO → Dashboard → Help, and click on Disconnect Account. After that, click on Connect Now to reconnect your account.


-
Check for Plugin Conflicts: There might be a conflict with another plugin or your theme. You can check for conflicts by following our guide on checking plugin/theme conflicts.
-
Manual Update: If the above steps do not work, you can manually update Rank Math PRO. Download the latest version from your Rank Math account area and then upload it via Plugins → Add New → Upload Plugin.


Regarding your second question, if you do not update the PRO plugin, it may lead to compatibility issues with future updates of WordPress or other plugins, and you might miss out on new features and security updates. It’s generally recommended to keep all plugins updated to ensure optimal performance and security.
If you continue to experience issues, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.
Thank you for raising this concern!

Hello,
It seems like you purchased the plugin with some other email address because we can only see the Content AI Expert subscription on your account.
Can you please share the email address which you used to purchase the plugin or you can search and forward the receipt from FastSpring.com so we can locate your account?
Back to your issue, one possible reason for this error is trying to update the PRO version of the plugin while connected to your free account.
