If language was already loaded in the database before, new text key might not be picked up.
Try to do the following:

1. Delete all text entries for english/account/newsletter in the admin language definition section (or database)
2. clear language cache.

This should resolve the issue.

Check your error log in AbanteCart. access log will not help.

I wonder what theme is that you have?

I think there is no setting yet. It would be good idea to have it. 

What can I check? Can you send your web store URL and coupon code?

Hello ioecc,

I can try to help ou, but I am not very clear of the requirement.
What do you mean by " leaving only one purchase button"? What is the other purchase button?
Do you want to redirect purchase to external sites for some products?

One option. You can edit date added on the product table directly with sql

You need to build a service infrastructure for this business. AbanteCart is just a code that can be configured and turned to ran as you want.

Looks like some CSS files are not loaded for fontawesome.
Do you use CDN?
Open your browser with the develop option on the network. See of all resources are loaded and there are no errors.

I think aatif1995 is talking about storefront API. Where do you see this message?

I think it is the best that payment is handled via app in that case.

Can you provide some example of screenshot? Sale will show up if conditions are set correctly. I have not come across of the issue you explain.

You need to be more clear with your question. I do not understand what you ask or try to do

Possibly that upgrade replaced/override some of your custom files.

What is a version of your AbanteCart?

Based on the classes col-sm-4 and col-sm-7 and min-width:240px; the imputes field should not be small.

Did you try to inspect HTML/CSS possibly some element is getting in a way?

This can indicate some issue with the cookies.
What browser do you use?
Can you try different browser?
