I've created an application which outputs a PDF report based on an HTML page using DOMPDF.
This works fine on my test server, but when I've migrated it over to the live server, none of the images show in the PDF. It's not showing a RED X - just nothing there at all.
I've checked that the new server meets the requirements using the config tool, and I've enabled the "leave images in temp" debugging option, and nothing is being created in the the temp directory.
Any ideas what might have changed to stop it from working?
