I was coding a long signup form, a very nice one, with the jQuery Validation Plugin, but it wasn’t working. I started to strip the code, piece by piece so I can identify what was causing the plugin to ignore the form and I came up with the most stupid error you will ever seen in your life (at least I think so).

Yes, a little dot that I don’t even know how to write with my keyboard. I even tried to replicate it and I couldn’t. 2 hours of coding wasted on this little bastard. Can you believe that?…
