Simple controller not working

Question

I am learning to make sense of magento and i am stuck.I have different stores and i am creating a controller but it seem it is not working and giving 404. Following is my code config.xml under /app/code/local/Ammardotcom/Helloworld/etc

    <?xml version="1.0" encoding="UTF-8"?>
<config>
    <frontend>
        <routers>
            <helloworld>
                    <use>standard</use>
                <args>
                    <module>Ammardotcom_Helloworld</module>
                    <frontName>helloworld</frontName>
                </args>
            </helloworld>
        </routers>
    </frontend>
</config>

and under app/etc/modules/ Ammardotcom_Helloworld.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Ammardotcome_Helloworld>
                <active>true</active>
                <codePool>local</codePool>
        </Ammardotcome_Helloworld>
    </modules>
</config>

while my file is called IndexController.php and it has following code under /app/code/local/Ammardotcom/Helloworld/controllers/

class Ammardotcome_Helloworld_IndexController
extends Mage_Core_Controller_Front_Action{
        public function indexAction() {
        echo 'Hello Index!';
    }
}

The module shows in backend but isn't loading, i am following @Alan tut

Answer 1

After many hours of hair pulling, i found out the reason, i misspelled my node in comparison to my folder namespace/module_name where namespace was Ammardotcome and xml node was Ammardotcom

You need to remove blank spaces from start of your config.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <frontend>
        <routers>
            <helloworld>
                    <use>standard</use>
                <args>
                    <module>Ammardotcom_Helloworld</module>
                    <frontName>helloworld</frontName>
                </args>
            </helloworld>
        </routers>
    </frontend>
</config>

If you add blank spaces at the start of your xml file, it may not load.

You have not defined module version in config.xml

<config>
    <modules>
        <Ammardotcome_Helloworld>
            <version>0.1.0</version>
        </Ammardotcome_Helloworld>
    </modules>
    .....
</config>
