Hello, I hope someone can help on this :S I just installed two prestashop http://test.lichtblick-brillen.de/prestashop/ http://test.mamapapababylove.com/prestashop/ and installed a new theme, both works fine and well. But suddenly both frontend and backend become blank pages. I turned the error msg on and I got this on frontend : Fatal error: Class 'ControllerFactory' not found in /srv/www/test.lichtblick-brillen.de/htdocs/prestashop/index.php on line 29 And on backend : Fatal error: Class 'Tools' not found in /srv/www/test.lichtblick-brillen.de/htdocs/prestashop/admin852/login.php on line 35 Thanks in advance!
