[v 2.4.2] One of the input fields does not seem to be valid.

Hi,

I'm using the latest version of Advanced book, which was upgraded from the previous version, I *HAVE* triple checked all files have been uploaded and the upgrading script had been done smoothly, however now not often, but sometimes I see this message when posting a message or comment: One of the input fields does not seem to be valid.

And I'm very sure that I've input everything correct, as well as the validation code, anyone can tell why this happens? Thanks!

Whats the address?

Hi Carbonize,

Thanks for your reply.. I've been away for 2 days so sorry for the late reply.

Finally I've find where's the "problem"

It's the validation code.. I had never realized that it was a small letter of "L", but I was always inputing the number "1" (one), because they look exactly the SAME, the small "L" on the image really looks like number "1" but itself, so that's why I said in the topic I'd triple checked and believed it was "correct".

Thanks anyway, after I realized that, there's no problem any more..

Regards.
