Your theme (Styled Store Pro) contains obsolete copies of some WooCommerce template files. You may have to update these files to ensure that they are compatible with the current version of WooCommerce. Suggestions to solve this:
Update your theme to the latest version. If there is no update available, contact the author of your topic to ask about compatibility with the current version of WooCommerce.
If you have copied over a template file to change something, then you will have to copy the new version of the template and apply your changes again.
