On some systems you'll get some error info if you go to the following URL while logged in as an admin:

ubbthreads.php?ubb=captcha&type=im&test=1

The only permissions that matter to the captcha images would be the cache directory as that's where it writes the temporary image.

Was hoping you'd read this one, i forgot the location of the captcha/gd test page :x

Rick, if I go to that test URL with GD2 enabled, I see the image fine.

However, if I go there with ImageMagick enabled, I get this text:
exec() is not available.

I checked permissions on my cache directory. It, along with all files within the directory, are OK.

Any thoughts? Thanks.

Looks like your webhost doesn't allow usage of the php exec command, which would stop webscripts from using it to utlilze utilities on the server (in this case, the ubb accessing the installed convert/morgify file)

Thanks, I'll contact them about it.

This is what my host said: "Can you send link to the file in question please make sure you're not trying to run php scripts from within the cgi-bin directory."

What would be the link I should send to help them out?

Thanks

In order for them to test it, they'd need admin access, maybe create a temp admin login for them and give them the test link.

Basically, the script just checks to see if the exec() function is available to php. I think they are thinking that the script itself is trying to be executed like a cgi script.

Thanks Rick, I will do that.
