Hello,
We would not recommend you to update the theme/plugins on production from start to avoid problems after update. It would be better to create a staging site first and make the theme update there, make sure that everything is ok and only after that update everything on the production.
Here is theme changelog – https://themeforest.net/item/woopress-responsive-ecommerce-wordpress-theme/9751050
Instruction for theme update you can find in our documentation – 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 (it will be reuploaded from a new theme package).
After update you may need to enter your purchase code to activate our new theme version and skip Setup Wizard.
Also, update all the 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/).
If you edited php files of theme, transfer changes into a child theme https://prnt.sc/j6xhoz.
If you still want to update everything on the production site without staging then do the backup of all the files and DB before the update. Then you’ll be able to restore backup if you face any critical error.
Regards
