Well, I've found the problem. It was related to file "config.inc.php" under "config" folder, at least for windows OS as in my case. The issue was in the entry: /* Directories */ define('_PS_ROOT_DIR_', realpath($currentDir.'/..')); It seems that windows isn't getting the path as expected, so, I replaced the function "realpath" with the function "dirname" that gives the "root path" of the application. The line must be as follows: define('_PS_ROOT_DIR_', dirname($currentDir)); In my case, it solved all my headaches and now Prestashop is running smoothly on my own server. Hope this can help to others!
