Human authorization is empty?

Hello, I just bought a human authorization plug-in and I can not make it work.
There is no picture, the test .png is empty, and after all the settings it is on
the correct place and seemes working (for new registration) but empty again.

I thought that my server does not have PHP - GD library, but.. it turns out it does, and
I think free type lybrary is auto instaled - ubuntu 12.04 server with Apache2 and PHP5.

What maybe the problem? Some restriction on server? Please help.

The first thing you may check: right mouse-click the picture, choose Properties, and check its direct URL.

Copy this URL to memory buffer and paste it directly in the browser's Address bar. In other words, directly go to this picture.

Most hopefully you could see the nature of the error displayed (if errors in your PHP are turned to be displayed).

If not, let us know...

Thank you Paul.
I did what you suggest and the result is just like the test png - empty background.

Here is a screenshot:

Here the screenshot, sorry
I checked the logwatch file, no this kind of errors. Maybe something with the free type?

It seems you just have PHP errors turned off...

Anyway, there is one more way to debug: modify addon_captcha.php and closely to the very end of this file, comment these strings of code that way:

//imagepng ($im);
//imagedestroy ($im);

and point to this image directly again after resaving the file; it will not output the image pointer, but most hopefully will report an error... Also, at the very top after opening <?php you may put:

error_reporting(E_ALL);

One other thing you could try as well: specify DIRECT disk paths to fonts under addon_captcha_options.php -> $fontsPath.

By default, it's relative:

$fontsPath='./fonts/';

but you could try to make it absolute, f.e.:

$fontsPath='/var/www/html/fonts/';

(it very depends on the path to your files on server, which you may know via getcwd() function of PHP - example below will not work, if you just copy/paste it).

The fonts path is set to absolute, I will just try the rest of your post :)



the path to fonts is

/var/www/om.bgyoga.com/forums/fonts

but I have another fonts folder at

/var/www/om.bgyoga.com/fonts

Could this be a problem?

Yes, stupid me, everything is OK now.
The permisions for the fonts folder were not right. Last week I had the same with a picture folder, took me half a day
to find out the reason :)

All the best and thank you.

Glad it works for you :) Enjoy.
(I'll put a note in readme about file permissions, interesting issue...)

Sometimes I "love" those self-fabricated problems, even if it cost me a few gray hairs =8). But the sense of achievement when you have then found their own mistakes is wonderful. ;-)
