TOPIC: No Captcha Image

Is this something you guys need to look into?

Hello Joseph,

Thank you for contacting our Help Desk!

The permissions of the php file should remain set to 755 as the ones that you have set up caused the following error message:

[2009-07-02 15:26:09]: error: file is writable by others: (/home/paragonm/public_html/components/com_comment/joscomment/captcha.php)

I successfully managed to revert them to 755. The actual cause for the problem is in the very php script itself:

[Thu Jul 2 15:53:19 2009] [error] [client 67.243.5.42] Premature end of script headers: /home/paragonm/public_html//components/com_comment/joscomment/captcha.php

When I tried to strace the file I got the following errors:

shmctl(1208385538, IPC_RMID, 0xba1b27d0) = -1 EINVAL (Invalid argument)
close(3) = 0
munmap(0xaf694000, 4096) = 0
unlink("/tmp/ZCUDgplfde") = -1 ENOENT (No such file or directory)

1) Share with us what version of PHP your webhost has installed

2) Make a phpinfo() dump by creating a new .php document on your webhost called "whatever123.php" (example) and paste the following code:...then go to yoursite.com/whatever123.php and File > Save As the resulting page, add it to a ZIP archive, and attatch the file here.

It might be a bug, it might not be. Are you on Shared or Free hosting perchance? Regardless, the phpinfo() dump will tell us whether your host is missing something that the captcha needs - specifically, GD2 and FreeType libraries (among other things).


I have no idea how PHP permission errors even occur to be honest. As long as you have a moderately up-do-date Joomla installation/configuration and you've configred FTP root install for Joomla, it baffles me why it happens to some...

the captcha.php should be 644. Please use the forum's search function and you will find all the necessary permissions.
