EME not working when WP changes from temp URL to actual URL

I’m moving my EME websites from a Windows server to a Linux server, and starting with a fresh copy of WordPress. I was using a temporary URL on the new Linux server to set up WordPress, and inserted these 2 lines near the top of the wp-config.php file:

define('WP_HOME','https://IPaddress/temporary-url/');
define('WP_SITEURL','https://IPaddress/temporary-url/');

I installed EME and copied the EME settings across and everything worked great.

I changed the nameservers for the domain so it pointed to the new Linux server, and changed the 2 lines in the wp-config.php file with the domain name:

define('WP_HOME','https://mysite.co.uk/');
define('WP_SITEURL','https://mysite.co.uk/');

The website loads fine now, and EME lists the events on the home page, but when I click on an event then it just says “No input file specified”.

Do you know why this is happening? Can I fix this without reinstalling EME, as I don’t want to have to copy across all of the settings, templates, locations, events, etc?

Thanks
