I'm still setting up my first AbanteCart store using ver. 1.1.6 that I downloaded a couple of weeks ago.

In early testing I used one of my email addresses to register for the Newsletter.  I tried to do a test order using my same email address by logging in as a Returning Customer, but the program won't let me.  It said: "Error: No match for E-Mail Address and/or Password".

So I tried to register again and it says "Error: E-Mail Address is already registered!"

So, I clicked "Forgot your password?" and entered my email address. The program sent me a new password. I tried to log in again as a Returning Customer using the password that the program just sent me, and I got this error:  "Error: No match for E-Mail Address and/or Password."  I tried again and double checked that I had the new password correct.

What might be wrong?

Hello. This is because by default in AbanteCart 1.1.6 You should enter Login name when create new account. Use it instead of email.
Also to change text "Error: No match for E-Mail Address and/or Password" go to admin and use global search to find it in language definitions.

I just looked at the shopping cart again and as you can see, the Update and Checkout buttons are way out of place, way over at the right margin. Did this happen with you, too, or is this another issue with my computer?

Yes I see issue on your site. Please check this post. Hope it helps to fix it

Just added product with options to shopping cart without any issues.
See screen attached

I'm just posting to this thread so that I get updates. I don't see any way to Subscribe to a thread without doing this. Is there a way?

Try to use NOTIFY button at the top near breadcrumb

I'm trying to set up flat rate shipping. On the "Extensions > Shipping > Flat Rate" page it shows a "Storefront Icon" being needed.

I'm also getting this System Message:  Language definition "default_flat_rate_shipping_shipping_storefront_icon" is missing for ""

There's no information in the Documentation about what this, what to do, etc.  Please add information about the Storefront Icon, what it is, what size it needs to be, where it will be displayed, etc., etc.

Thank you

Hello. 'Storefront icon' not required. Add it if you want to display some image when checkout.  Just try to add any image and check checkout process.

I just thought I would throw this out there. I notice some users are not seeing changes after they have made them. I know in my case, I have to refresh (use the circular arrow on my browser's address bar) my storefront before I will see the change I have made because my computer caches the last viewed screen. Even if I have closed the storefront and re-opened it I still have to hit refresh. This may be the first thing to try if you do not see your change right away.

Hello. This is related to browsers. Each browser use different ways to cache sites. In FireFox use Ctrl+F5 to refresh and see CSS and HTML changes but in Chrome you need to use it at least 2 times to see last changes. Even more modified .htacess file can be used to control caching between the browser and the Apache web server. And even more if user connect site to content delivery networks - You need reset  images and CSS cache manually in the network admin panel.

1)Automatic Inventory Control

Inventory control is carefully built in as the core of eCommerce System. Just set the inventory balance for each of your products and your shop will automatically manage the inventory for you.

Customers will not be able to purchase a product when inventory is at zero. Telling your customers 'Sorry, we are out of stocks, here is a refund' will be a thing of the past.

Hello. We already have stock system. Each product and even each product option value have own quantity. Please read Stock processing configurations manual
And Yes 'Customers will not be able to purchase a product when inventory is at zero' if you set up stock setting correctly
