I have tried installing simple checkout on an already modified site (localhost) using option 3. Got error when trying to run the sql.
tried it again on a fresh install (localhost) and same problem
Error
SQL query:
INSERT INTO `configuration_group` ( `configuration_group_id` , `configuration_group_title` , `configuration_group_description` , `sort_order` , `visible` )
VALUES ( 7500, 'Checkout', 'Settings for single page checkout', 16, 1 ) ;
MySQL said:
#1062 - Duplicate entry '7500' for key 'PRIMARY'
when i try to use it I have little red boxes with numbers in after each textbox (the boxes will turn green after typing in the textbox)
do you have any idea what i am doing wrong? I don't know anything about sql and very little about php
