Theme & Plugin does not work out of the box

Hi,I have installed a fresh copy of Wordpress and installed myticket.zip and then myticket-plugin.zip - the site doesn't work? Here is a list of issues:Upcoming Events is blank > https://ljhwebsites.co.uk/upcoming-events/Events is blank > https://ljhwebsites.co.uk/events/ and get this message in the page editor "Your site doesn’t include support for the "myticket-events/listing-01" block. You can leave this block intact, convert its content to a Custom HTML block, or remove it entirely."Search > https://ljhwebsites.co.uk/search-events/ is blank and same issue as above "Your site doesn’t include support for the "myticket-events/listing-01" block. You can leave this block intact, convert its content to a Custom HTML block, or remove it entirely."Please let me know ASAP what is going on and how it can be fixed.
