Sometimes you cannot update a WordPress or WooCommerce plugin via your backend using the auto update option. It happens. My advice: ignore it and update manually. Only if the issue persists and the lack of auto update is starting to annoy you multiple times, escalate to a support queue.
A manual update for a paid WooCommerce extension is done as follows.
- Go to your WooCommerce account and download the extension.
- Unpack the extension.
- Upload via a FTP client. I use FileZilla in my video.
- Overwrite the existing files completely.
- Alternatively you can use this super convenient plugin to update your plugin manually from the WordPress backend.
