Install, update & configure

Everything you need to get the module running, keep it updated, and set it up for your store.

Before installation

This module does not automatically refund orders, restock products, void payments, or make legal decisions. It provides the request workflow and admin tools so the merchant can review each case.

Installation

1
Upload the OCMOD package

Go to Admin > Extensions > Installer and upload the extension file. Wait until OpenCart confirms the upload has completed.

2
Refresh modifications

Go to Admin > Extensions > Modifications and click Refresh, so OpenCart applies the OCMOD changes.

3
Clear theme and modification cache

Go to Admin > Dashboard > Developer Settings and clear the theme, SASS, and modification caches. Buttons vary slightly by OpenCart version or theme.

4
Install the module

Go to Admin > Extensions > Extensions > Modules, find Ninawebs EU Withdrawal & Cancel Button, and click Install.

5
Set admin permissions

Go to Admin > System > Users > User Groups, edit your administrator user group, and allow access/modify permissions for the module and its request management screen.

6
Configure the module

Enable the module, enable guest order links if you allow guest checkout, choose which order statuses allow or hide pre-dispatch cancellation and withdrawal/return requests, configure notification emails, then save.

Optional: create a dedicated order status (e.g. Customer Cancelled) under Admin > System > Localisation > Order Statuses to use as the automatic holding status for eligible pre-dispatch cancellations. This helps prevent staff from accidentally packing or shipping an order after a cancellation request.

Updating

1
Back up first

Create a full file and database backup before updating.

2
Upload the new package

Go to Admin > Extensions > Installer and upload the new package. In most cases you do not need to remove the old uploaded package first.

3
Refresh modifications

Go to Admin > Extensions > Modifications and click Refresh.

4
Clear caches

Go to Admin > Dashboard > Developer Settings and clear the theme and modification caches.

5
Re-save the module settings

Open the module settings page under Admin > Extensions > Extensions > Modules and click Save.

6
Refresh layouts and order statuses

Click the "Refresh layouts and order statuses" button on the module settings page.

Don't uninstall before updating, unless support specifically asks you to. Uninstalling can reset module settings (selected order statuses, notification email, the guest-link token secret) and may break guest links created before the upgrade. Existing request history stays in the database either way, but settings do not.
Want to remove the old package from the Installer list to keep it tidy? That's fine, just don't refresh modifications in between. Safer sequence: remove the old package, immediately upload the new one, and only refresh modifications once the new package is installed.

After updating, check:

Uninstalling

Disable the module first under Admin > Extensions > Extensions > Modules, then uninstall it and refresh modifications. Request and audit history tables are preserved so existing records are not lost, but module settings (order statuses, notification email, the guest-link token secret) are reset, which can break guest links created before the uninstall. If you are updating rather than removing the module for good, use the Updating steps above instead of uninstalling first.
