Word Press Website issues since moving to a new host

We have experienced some issues with a website since migrating to a new host.

Traffic seems to be fine but our level of transactions are very seriously down. I have run checks on all functions and everything seems to be operating but I have no idea why we would have such a fall-off in business. So there is probably some lingering technical issues post-migration.

Our transactions come in through Forminator and Woocommerce

The website is https://anthology-magazine.com/
