Featured Images not Imported on WP MultiSite

Hi

I have a site here where the images are pulling through ok

https://hunpodcasts.vickybower.co.uk/

I replicated the site onto a WP Multisite but the images are not pulling through

https://hunpodcasts.co.uk

The only difference between the two site are that the second one is on a Multisite.

The img tag is clearly not there.

Any ideas?
