TOPIC: Captcha is not showing

Hi.. I'm upgrade my joomla! to 1.5.9. My joomlacomment (3.26) seems to work but isn't showing the captcha image, just says "Security Image"

How can I solve it? Thanks

Sorry for my english...

The best way to solve it is searching the forum
Another good way to start is to give a link to your web site.

I looked at the forum, but did not find the solution. The site's url is www.lasemanaonline.com.ar

One example is http://lasemanaonline.com.ar/inicio/index.php?option=com_content&view=article&id=722:crimen-de-las-amigas-convocaron-a-expertos-para-determinar-a-que-hora-mataron-a-solange&catid=55:tribunales&Itemid=280

lasemanaonline.com.ar/inicio/index.php?o...ribunales&Itemid=280

I don't see and comment form?

I'm having the same issue. I have installed JoomlaComment 3.26 on Joomla 1.5.7 and the Captcha is not showing.

See www.pgoledb.com/index.php?option=com_con...eneral-pgnp&Itemid=1

Please help.

Konstantin please search the forum for solution.

You most probably don't have the gd library installed.

Daniel, I appreciate your quick response. I googled for "install GD library" and found:
php_gd2.dll ... is not enabled by default. To turn it on, the user may simply uncomment the line "extension=php_gd2.dll" in php.ini and restart the PHP extension.

Is this correct way to install GD? I contacted support of my hosting company (jiffynet.net) asking them to enable GD for me (since I could not locate php.ini).

Would you correct me if installation of GD should be performed differently?
Thank you!

This is the right way to perform the installation.
What you need too beside the GD library is the freetype library( www.freetype.org/ )

I have sent an inquiry to the hosting support. Btw, while waiting for their assistance with GD library, I have two questions:
1) howto install FreeType 2.3.8 on the host web site? (hopefully their support will be able to do it)
2) are you planning to implement different types of Captcha? It could be nice in order to reduce risk of breaking it.

Thank you for doing the great tool!

the freetype library should be configured from your host.

Yes, we are planning to implement different types of Captcha, but first in release 4.1 .

Hi Daniel. Is me again. Please help me. I´m looking at for a solution but I don´t find it. Captcha isn´t showing yet. Maybe the cause is that I move my site to a new server... I don´t know. Please look at this: http://lasemanaonline.com.ar/inicio/index.php?option=com_content&view=article&id=880:forcejeos-en-una-manifestacion-a-favor-de-palestina-frente-a-la-embajada-de-israel&catid=88:notas&Itemid=296

lasemanaonline.com.ar/inicio/components/...f64cc6d9375f2b511dda

Look at the server error log and also check the threads in the forum about captcha problems.

Thanks Daniel. I consult with the hosting provider to fix the problem

Daniel. I am sorry to bother again. I`ve been looking at the forum for help with my trouble, but I can fix it. My host provider did not give me solution. I change permissions but still have error. "Fatal error: Call to undefined function: imagettfbbox() in /www/docs/lasemanaonline.com.ar/public_html/inicio/components/com_comment/joscomment/captcha.php on line 59"

Hey Fernanda!
Fatal error: Call to undefined function: imagettfbbox() in means that the GD library is not installed. Look in your php info(in joomla's backend) do you find gd library there?

Daniel, I find this
