The migration module didn't work for you, right?

Simply replacing code files doesn't work for the reason you see.

What you can try is to do a fresh thirty bees shop installation (into a subfolder), using a fresh database. This should give a working shop.

To recover all the stuff from the previous shop, open config/settings.inc.php in both, new and old shop, then transfer database settings (those beginning with _DB_...) from old to new. Having this done, the new shop should show all the products from the old shop ... except pictures.

To get pictures, too, move/copy img/p from the old to the new shop, replacing the previous folder there.

Chances to get a working shop then are good.

One can move a shop from one folder to another folder by moving all the files, but one also has to go to Backoffice -> Preferences -> SEO & URLs -> Set Shop URLs and adjust Base URI there.

All this said, any chances to get the migration module debugged? What's going wrong after uninstalling custom modules?
