Ext.onReady(function(){    
Ext.QuickTips.init();    
Ext.container.Viewport({
    layout:  'border',
    id: 'mainbody',
    items: [
    {
        region: 'North',
        id: 'north',
        collapsible: true,
        title: 'North',
        html: 'North'
    },
    {
        region: 'south',
        id: 'south',
        collapsible: true,
        title: 'South',
        split: true,
        html: 'South'
    },
    {
        region: 'center',
        id: 'center',
        collapsible: true,
        title: 'Center',
        split: true,
        html: 'Center'
    },
    {
        region: 'east',
        id: 'east',
        collapsible: true,
        title: 'East',
        split: true,
        html: 'East'
    },
    {
        region: 'west',
        id: 'west',
        collapsible: true,
        title: 'West',`enter code here`
        split: true,
        html: 'West'
    }
    ],
    renderTo: Ext.getBody() 
});

The linking to the pages are correct, I cross checked several times

Thanks in advance !

Solution

If you are using that code exactly as it appears there, the line that says "title: 'West','enter code here'" will definitely break it. Remove the 'enter code here' or comment it out as //enter code here. It's near the bottom of your javascript example.

If you're not using the code exactly as it appears, test it at jsfiddle.net. If it works, it's definitely your paths.
