OK, after some more testing:
So cfg-id is 27, language-id is 1 and then title as you defined it.
So the statement needs to be:
INSERT INTO configuration_group VALUES ('27', '1', 'VAT-Mod', 'VAT-Mod options', '27', '1');
Whether you choose 1 for english, 43 for austrian (zen-cart.at which I use) or maybe 49 instead of 1 for a german version is up to you.
OK, that was my theory.....
Without the additional 1 or whatever, the following error is shown when I try to run the command:
1136 Column count doesn't match value count at row 1
in:
[INSERT INTO configuration_group VALUES ('27', 'VAT-Mod', 'VAT-Mod options', '27', '1');]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.
After installing a fresh 1.37 (german version) I applied the patch, copied the files, but the VAT-field still isn't displayed when registering. Neither in english, nor in german.
So I checked the database again. Found all the entries from the SQL-patch, so this should be OK.
Checking entries at client details config -page: no options available.
The client's record and the order record contain VAT as expected....
Any ideas???
