I too have moved from 1.3.8a to 1.3.9f and have run zc_install for update on the test database I was using while doing a fresh install. Then I installed the database and proper configure.php for that 1.3.8a database. Now FEC 1.8.4 does not work. So I guess something in DB.

SQL patches are a way of putting information into your database or changing its structure. Once done, they're done, and the results are carried forward (unless they're subsequently undone!).

You haven't given any explanation as to why you think you're having a database problem. Upgrade problems with mods are more usually because code changed by the mod has been overwritten by core file changes. Have you reapplied the FEC files since you upgraded?

If so and you're still having problems, them I recommend posting in the FEC support thread, as you'll help from people who know that specific mod.
