Still cant update order quantity

Hello. Please follow llegrand solution

hmmm  -  it appears differently on different products -  some work,  some don't
.....
Perhaps compare the two different products and see how settings are different.

Please open product edit page in Admin-Catalog-Products and search for Maximum Quantity setting.
Maximum Quantity - Set a limit on quantity that can be selected per each order. Set it to 0 = no limit   

Hello. Very strange behavior. Please clear AbanteCart cache. Try again to save layout and check for AbanteCart error log

Hi, I have switch on the paypal, paypal express and default banktransfer.

Paypal has appear for selection, but the bank transfer has missing, is there any setting was wrong?  Thank you

Hello. Check Bank Transfer setting especially:
Bank Transfer Instructions - it is required
Location
Total Order Minimum
Total Order Maximum

Thank you so much Basara!! U saved my day, literally I can now sleep in peace

Cheers mate!

Sleep in peace, bro 

Thanks @Basara.  Now that you explain it it makes pretty good sense.

Do you know if it is possible to:
1.)  Display 4 denominations of vouchers as "products", and have these vouchers displayed as "featured" or similar on the home page?
2.)  Is it possible to discount these vouchers.  Example if I want to offer a $100 for sale for $50?

Hello. Hmmm there is no way to do this in simple way using extension but You can do the following
1. Create new product in Admin-Catalog-Product with name `Gift Certificate 100 USD` with 100USD price and set it to be Featured and add specials price if needed
2. Next on the product edit page go to Options Tab and Create several new required options with Element Type INPUT:
From Name
From E-Mail
For Name
For E-Mail
This will force customer to fill required fileds before checkout. After order confirmed this details will be in Admin-Sales-Order detail page

3. After someone purchase this product you should manually create Gift Certificate Amount 100 USD in admin-Sales-Gift Certificate with new  (From Name/From E-Mail/For Name/For E-Mail) details and send email manually with Gift Certificate code

Hope this way help You.

Another way is to modify extension some how to attach gift code to product and send email automatically after order with Gift Cetificate Product set to Completed.

My basic question is, if a registered customer wants to checkout as guest using the same e mail, can they do so? I am stopping the work on migration at the moment hoping the answer to this is yes and we can go ahead.

Answer is Yes.
Anyway you can install AbanteCart and check this before migration. If You have Softaculous in your hosting cpanel the installation takes about 1 minute

1> If i setup 3 stores as multiple stores, all the extension i buy is available for all 3?

Usually Yes, but please read license agreement when install extension

2> i want one of the store to setup as product can be viewed only if customer logs in. can i do that?

For now we have only quick setting  to hide prices if user not logged on (Admin-System-Settings-Checkout). Also You can set up different promotions (special prices) for each customers group

3> when i upload, i want to make those products available to all 3 stores, can i do that? also if i have one store setup already, can i copy part of those products over to other store?
let me know.
thanks.

When you edit products you can select the stores to which this product is associated by checking the checkbox next to the Stores from which you want the product to be available.

Hi.
By default in AbanteCart pre-installed only one Location USA. To create new one go to Admin-System-Localization-Location
