Hi! I'm newer in codeigniter and I have searched on web an example of code captcha that works. Many examples not working, but an example maybe could work. This example is here http://runnable.com/UXb8GazDrMMiAAEA/how-to-add-a-captcha-in-codeigniter I want to use this example, but I don't know how to configure the files from application/config Could you help me? If you know an example that works you could say me the address on web. Thank you very much!
