You then click on the install button. Which, puts some records into the database, including the menu items for the configuration.

But you need to then use the second sql statement to show the menu items in the configuration menu items.

The order is important. And it is important that the module is fully uninstalled before you start. That means that the files are removed and the database entries are removed.

I think that something else is going on here. If you are getting that error to that particular function as undefined then something is not installed correctly. As I say, my instructions were based on starting from a clean install so if files and database have been altered before that then it is hard to comment on those changes.
I see, so it may not be working because I used the old database? I can't import 600 products any other way. Way too much work.
