                                    </vivassms>
                                </children>
                            </config>
                        </children>
                    </system>
                </children>
            </admin>
        </resources>
    </acl>
</config>

I've added these three children tabs to the created new tab SMS Center but when i click on the About tab i got error 404 ON MY FRONTEND. This is awkward. Why i got redirected to the frontend ?

Can you please help me out to create a simple new custom page in the admin panel where i want to add a simple text?

Thanks in advance!

There are two things you will need to get going: a controller, and proper paths to the controller in your adminhtml.xml.

Here is what you'll need in your controller for the first link:

class VivasIndustries_SmsNotification_Adminhtml_MagesmsController extends Mage_Adminhtml_Controller_Action
{

    /**
     * Grid action for ajax requests
     */
    public function sendsmsAction()
    {
        $this->loadLayout();
        $this->_setActiveMenu('vivassms');
        $this->renderLayout();
    }
}

This will get you a blank page within the Magento admin.

You should also updated your adminhtml from this:

<sendsms translate="title" module="smsnotification">
    <title>Send SMS</title>
    <action>adminhtml/magesms_sendsms</action>
    <sort_order>1</sort_order>
</sendsms>

to this:

<sendsms translate="title" module="smsnotification">
    <title>Send SMS</title>
    <action>adminhtml/magesms/sendsms</action>
    <sort_order>1</sort_order>
</sendsms>
