So apparently comparing clean 1.3.7 files to what we have on the server isn't going to resolve this problem if it's a database 1.3.5 to 1.3.6 problem. /zc_install tells me we are current on the database to 1.3.8. There are no unchecked checkboxes. Everything else works just fine on the site as far as we can tell.

I have the patience but obviously not the skills for this job. Thank you for your help and we'll just continue using it the way it's been so far.
