Hello, i installed bigtreecms with manual on windows 7 with xamp, after install i clicked to install example website but after that when im putting "http://localhost/bigtree/site/index.php/" into address line, i see only "Fatal error: Class 'DemoTrees' not found in C:\xampp\htdocs\bigtree\templates\basic\home.php on line 2" ...this path is ok but i dont know how to fix it. If i try to open admin pannel, my path : "http://localhost/bigtree/site/index.php/admin.php/" i get back only "Page Not Found , 404 Error, can you please help me with this install?

Thank you so much,

Martin
