Images not linking in Dashboard but showing in site?

Hi, After migrating from another server to a new server with the same URL above all the images are not showing in the dashboard but are showing on the site? Also when i upload new images they are uploading but can not be viewed in the dashboard (just shows a question mark).

I have enabled access to the back of the site.

Could you take a look at this for me?

Thanks
