After each and every fiddle with the settings, I sent a test email to myself from the sales section of the Admin menu. It always fails, and unfortunately AbanteCart doesn't have a test system button on the configuration page to make the configuration process easier. I've never had problems with other web programs, just this one.

Is there information about NON SMTP sending anywhere?

I did an inline upgrade from 1.2.12  to 1.2.13 that posted a "failed" message but I noticed that the footer stated that I had installed the latest version was. How do you force a upgrade reinstallation to be sure all of the new files, etc. are installed correctly?

When I sort the products by status, sorted so that off is at the top, some products are there and the ones I add using the cloning method or at least some of them are not.

Yes, 1.2.10.

I think that by "remove" you mean select the lines with indexs and DROP them and recreate?

I'd add that these may not drop -
The column name 'group' is a MySQL reserved keyword.
The column name 'key' is a MySQL reserved keyword.

When I backed up the database and did a drop on all, I got this message -
#1090 - You can't delete all columns with ALTER TABLE; use DROP TABLE instead
ALTER TABLE `ac_settings` DROP `setting_id` ,
DROP `store_id` ,
DROP `group` ,
DROP `key` ,
DROP `value` ,
DROP `date_modified` ,
DROP `date_added` ;

I deleted group and key individually, and re added. They listed as Primary Keys so nothing changed. The 1.2.7 update.sql file will not import so I'm back to where I began.

I think that the template files are in abantecart-src/public_html/storefront/view/default/template/ or the entire section under ...storefont?

Are they the only files to be copied to the working site? If so, I don't see a download link and right click doesn't copy the file tree. I do not see a way to download folders.

Is it a special GitHub method?

I've tried to do a manual update using the PHPmyAdmin interface and get this message -

#1061 - Duplicate key name 'unique_id in the ac_settings_idx settings. I've looked at the structure keys and compared the settings to another AbanteCart structure. The working system does not have primary keys for either Group or Key. How is the Group key removed as it may be the problem.

I have only found one reference to this phrase - FULLTEXT INDEX `ac_settings_idx` (`value` ASC) apparently to setup the ac_setup.

See photo.

If not how do I fix the problem? I can restore prior versions of the MySql database and the original 1.2.6 files.
