Hello,
At first, you need to update theme to 3.2 version that is compatible with latest woocommerce version –
https://www.8theme.com/demo/docs/woopress/#!/installation_upgrade.
Before uploading theme files delete “woocommerce” folder, which is located in wp-content/themes/woopress/ to avoid problems with old files.
Don’t forget to create backup of your files and database before starting update process!
You need to enter your purchase code to activate our new theme version and skip Setup Wizard.
Also, update all required plugins https://www.8theme.com/download-plugins/ (To update free plugins just click on update link from your Dashboard (Plugins > Installed Plugins). To update premium plugins, connect to your server using FTP. Copy extracted plugins folders into wp-content/plugins/).
Regards
