I want to add a popup to my website to show a special offering. I've found a couple of free open source jquery popups. I have the zipped files containing all the coding files but which file in the Abantecart platform do I put the jquery code and the other code for my popups. The instructions for the popups say to put the codes in the header and footer files.

I've examined the header.php file in /storefront/controller/common/  and do not see a Jquery code. I see that it says to customize the file, go to the abantecart.com site for answers.

Please let me know how to add my Jquery popups.

Every time I do a test order and create a customer with a fake email I get some kind of duplicate error message like the following:

SQL Error: Duplicate entry '205106-1' for key 'PRIMARY'
Error No: 1062
SQL: INSERT INTO abwk_order_data (`order_id`, `type_id`, `data`, `date_added`) VALUES (205106, 1, 'a:2:{s:3:\"uri\";s:16:\"glogan@email address\";s:6:\"status\";s:1:\"1\";}', NOW() ) in home/smallbu4/public_html/WEBSITE NAME/core-database-amysqli.php on line 106   

The error message is telling me about a problem in the amysqli.php file. How do I fix this problem?

I've installed Abantecart version 1.2.7. I've notice in doing an Order that when customer receives order summary email that the verbiage after "The comments for your order are:" are shown twice in the email. So for instance, it shows the mailing address to send the check two times. This does not look good.

Please advise how to delete the second showing of the comments.
