I am currently reading a textbook on Joomla and the book offers a ready testing site that I want to see and play around with. But I already installed Joomla in a folder called joomla150 on my localhost server and started developing a website. Everything works fine, except I can't test the ready website. I put the ready website in a folder inside the joomla150 folder along with the other joomla folders and files. When I access the index.php of the ready site nothing is displayed. Now this may sound like a silly question but I want to launch this ready website and I can't figure what to do. I don't want to delete the current website I have been developing, but I will if I have to. How do I load it with joomla without having to reinstall the whole thing? Isn't it possible to work on two websites at the same time from one joomla installation?
