Moved host, no longer showing images

Hi,

I’ve been using FileBird for ages and it works really well to organise my images. I moved to a new host yesterday and whilst the list of folders displays only one image ever shows and the rotating wheel next to where is says “bulk select” never stops. This error displays in console:

My upload path used to be /home/gzkpcl1i6pan/public_html/wp-content/uploads and I’ve changed it to /home/customer/www/mywebsite/public_html/wp-content/uploads

What do I need to do to get it working again?
