Wrong Link on main category items after migrating website

Hi – I am using the accordion menu here: https://www.manororganicfarm.co.uk/shop-online/ after I migrated the wordpress website from the test site to the live site, some links are still trying to link to the old test site so they’re not working properly – how can I fix that?

Thank you!
