I just moved my site to a new server and now all of the sudden little things my client use to do to make his job easier are no longer working. For instance, when he checks multiple orders and then picks the print option it takes him to a page where he can print those orders out. Then he clicks back and with the same items selected he 'marks them as read' - the problem is, on the new server when he clicks back the checks are gone. We do not get an expired message or anything, they are just empty like it was never filled out.
Im guessing this has to do with the apache / php configuration, but more on the apache side if i had to guess.
Does anyone know what is causing this to happen and what I can do to prevent it?
