Images not uploading on migrated site

Hello,

I have taken over/helping with a perch site that I have migrated from one server to another. The original database was also migrated.

The issue is that users are now unable to upload new imagery to templates, the user gets a green alert box informing them the page has been updated but the image is missing. Text is fine as is uploading to the asset bank but adding a image to a template (either via upload or asset bank) does not work. I did managed to fix one template by changing the id of a image tag then changing it back but that wiped the content of the rest of the template.

Has anybody come across this before?

I have tried debuging the template when submitting and it outputs the image tag id in red, in the debug output.
