Opencart homepage fix "The page you requested could not be found

Hi

Upgrading a site to Opencart 3.0.3.2 and updating the theme at the same time, we cannot get the homepage to function as it should, instead getting the message "The page you requested cannot be found."

Given up trying to resolve so looking for an Opencart expert who can fix it quickly.

The issue can be seen on this development version of the site...

SFTP & Admin access will be available to whomever can get this fixed as quickly as possible, some further homepage set-up work also may be required but we can look at that one the main issue is resolved.
