Hi, guys. I'm new to Ajax, so I'm having a problem. When I press the supposed link to use Ajax, it shows an error message with the error parameter empty. What am I supposed to do?
I already tried to use base_url instead of site_url and it's no use. The structure of the click function is ok, I already tested it.
Thanks.
