Acrobat is giving the error "An Error exists on this page"
When I open my PDF I am getting the following error:
Sometimes during PDF creation very small fragments of information are created that Acrobat does not know how to handle, so it gives this generic error.
Download the Action List "Remove Tiny Objects" from below. It does not work on every file, but it if the problem is in fact as described above, it can eliminate the error on open after the Action List is run.
