Hi,
The first thing you need to know about modifying the product grid is that AbanteCart uses several types of controllers.
The grid configuration itself is defined in the page controller — in your case, `catalog/product`.
This configuration is passed to the `common/listing_grid` controller, which renders the grid using jqGrid.

Right after loading, an AJAX request is sent to a response controller. You can find all the response controllers for grids under the `responses/listing_grid` path.

As you've probably guessed, at each stage of the code execution path, you can make changes to the controllers using our hook system.
Each controller has calls like `$this->extension->hk_InitData()` or `$this->extension->hk_UpdateData()` (there are actually more),
which allow you to modify public properties of the controller from a hook, both before and after execution.

So, to add a column, you need to modify the configuration before the `common/listing_grid` controller executes.
(The configuration data contains a `table_id`, so you can easily detect which grid is being called. In your case, it's `'table_id' == 'product_grid'`).

You’ll also need to modify the response controller `listing_grid/product` to include `title` in the data list.
As an example, check the method `public function onControllerResponsesListingGridExtension_UpdateData()` from the `avatax_integration` extension.

It’s best to work with Xdebug so you can see which data is available at each step.

For more details on how hooks work, refer to (https://abantecart.atlassian.net/wiki/spaces/DOC/pages/17793156/Hooks]our documentation:

I think you can combine additional applications/software to check traffic to your website.

Have you checked if any plugins, modules, or themes use the .webp format? It is possible that during the reinstallation, the system automatically reuses old data or temporary files (cache) that are still left over from the previous version. Did you back up the entire /resources/image/ folder, or just the database data?

My second question is, on the checkout page, it keeps saying "Error: No Shipping options are available. Please contact us for assistance!".

I have no idea why it keeps saying this - I activated ship by weight and also paypal is available as a payment method.

Please help, thanks

because it's hardcoded in tpl
