Hi, I have try to enable Captchas in comments but I see only a White square with no Captchas in.
Where I can look for that ?
Thx !

Hi!
What's your URL? Maybe you configured white text on white background?

Hi!
It seems your server'S PHP GDlibrary is not able to parse the ".ttf" truetype files in the spamblock directory. Did you upload those .ttf files, are they existing and readable?
You might need to ask your hoster if truetype support is properly enabled and setup in PHP.
Best regards,

Hi!
Other systems like phpnuke might emit Captchas completely different! Is phpnuke also using .ttf files to create a captcha?
I have change to grey the background to see and I see nothing... I see some dot in the box if I put scrambled.
Definitely your PHP gdlib is not able to parse the .ttf files of the spamblock plugin in this case. Because the rest works, but not rendering TTF.

I have talk with my hosting guys but they dont know what I mean ... I am on a Windows 2003 server. You know where I can search to have the mothod to config the server to make it working ?
I see .png in the folder ... the Captchas can use these .png instead of the .ttf ?

Hi!
Maybe you could search for some PHP scripts that use TTF Fonts to render images? Maybe with those scripts you can see if it generally works on your server.
It might be that on a Windows Server, TTF generation is not really possible. I have no experience with that.
I see .phn in the folder ... the Captchas can use these .png instead of the .ttf ?
That would only work if GDlib is not available on your system, as the fallback is only used automatically. But the captcha fallback is really easy to bypass.
