I keep getting this error on files that previously passed preflight even though I'm using the same preflight profile:
Trim box width is 307.86945 mm, should be equal to 215.9 mm, Trim box height is 244.72223 mm, should be equal to 279.4 mm. How can I fix it?

This is the Trim Box which represents the finished trimmed size of the job.
If it's incorrect you need to change the Trim Box, but you may additionally need to adjust other related page boxes like the bleed box and crop box.
Also you may have to adjust the page content if the page is too big or small.

The first question though is, is the page the correct size?
