Thank you so much for using our theme Capacious. The above message you shown is not the issues exactly and not the error as well. If WooCommerce is not installed and the dummy data you import, this message will displayed. So, don’t worry, it’s not the issues. If you want to get rid of this, you can reset the database, install the WooCommerce plugin and import the dummy data again. Now, you will not get anything error message.
If you have any queries, let us know. We will do our best to solve your queries.
