could be something else?
I checked and upload all Portuguese files and still the same issue.
I changed one TEST user to English and try and still not showing the captcha even if his language is English.
I can see a blank space on this file:http://www.MY_SITE_THAT_YOU_KNOW/forum/ubbthreads.php/ubb/newpost/Board/6
(replace the mysitethatyoukno)
but I could not find where that line is coming from.
and on that page, for a NEW USER, the captcha is displayed.
any other ideas?
