Samples dhtmlxLayout Integration with DHTMLX components

I’ve just downloaded dhtmlx Layout and Windows. When I try to open layout sample files related to Integration with DHTMLX components I just get empty cells. I’ve tryed using an apache server and a browser directly on the samples files but the result is always cells with empty content. Is there something I’m doing wrong? When I open the same files on the dhtmlx website, these show content.
Can you help me please.

Please, try to open your page from the web server but not using the local path.
dhtmlxGrid uses the ajax request to load the data.

I’ve also published it online but I get the same results.
When I access the demo on dhtmlx website everything shows properly.
Can you please help?
