This hack will activate all the order status on all states. What I mean is the Status dropdown in the Comment History, by choosing the desired status and Submitting the Comment. We can change the status of the order to Complete or Closed or any available status for that matter.

All we have to do is edit the config.xml under the magento_folder\app\code\core\Mage\Sales\etc\.

Then find the <states>code block. That’ll look like:

<states>
<new translate="label">
<label>New</label>
<statuses>
<pending/>
</statuses>
</new>
<processing translate="label">
<label>Processing</label>
<statuses>
<processing/>
</statuses>
</processing>
<complete translate="label">
<label>Complete</label>
<statuses>
<complete/>
</statuses>
</complete>
<closed translate="label">
<label>Closed</label>
<statuses>
<closed/>
</statuses>
</closed>
<canceled translate="label">
<label>Canceled</label>
<statuses>
<canceled/>
</statuses>
</canceled>
<holded translate="label">
<label>On Hold</label>
<statuses>
<holded/>
</statuses>
</holded>
</states>

And change this with the code below:

<states>
<new translate="label">
<label>New</label>
<statuses>
<pending/>
<processing/>
<holded/>
<complete/>
<closed/>
<canceled/>
</statuses>
</new>
<pending translate="label">
<label>Pending</label>
<statuses>
<pending/>
<processing/>
<holded/>
<complete/>
<closed/>
<canceled/>
</statuses>
</pending>
<processing translate="label">
<label>Processing</label>
<statuses>
<pending/>
<processing/>
<holded/>
<complete/>
<closed/>
<canceled/>
</statuses>
</processing>
<complete translate="label">
<label>Complete</label>
<statuses>
<complete/>
<pending/>
<processing/>
<holded/>
<closed/>
<canceled/>
</statuses>
</complete>
<closed translate="label">
<label>Closed</label>
<statuses>
<pending/>
<processing/>
<holded/>
<complete/>
<closed/>
<canceled/>
</statuses>
</closed>
<canceled translate="label">
<label>Canceled</label>
<statuses>
<pending/>
<processing/>
<holded/>
<complete/>
<closed/>
<canceled/>
</statuses>
</canceled>
<holded translate="label">
<label>On Hold</label>
<statuses>
<pending/>
<processing/>
<holded/>
<complete/>
<closed/>
<canceled/>
</statuses>
</holded>
</states>

After that, It is important to refresh your cache.

Why can we delete cancel order only?
That’s because deleting a complete order breaks links with invoices and shipments and could creates a lot of troubles.

Go to Delete Orders Extension.

Install this extension via Magento Connect Manager.

Magento Connect -> Magento Connect Manager

This is Kaspersky Internet Security 7. This version has a license until 2011, if Kaspersky doesn’t catch it by then. I tested this out, the patch doesn’t contain any virus. Download it here. Read the Kaspersky.txt for the procedure on how to activate your Kaspersky Internet Security.

If you already have a Kapsersky installed in your system. You will have to uninstall it first. If add/remove program files won’t work. I have a kaspersky remover here.
