Hi there,
I understand that you are not seeing the All orders tab.
@marcus313 May I know if you are also using Sucuri. If so, does deactivating it fixes the problem as in @jooray ‘s case?
If not, then in order for us to get a better idea of your setup, please share a copy of your site’s System Status.
You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.
