no capcha image is displayed

Hi can you check the following documentation.

Thank you

Hi mbrsolution

Thanks for the reply.
I have gone through this page before I wrote to this forum. I could not find any solutions. Even my web site hosting provider could not help me. They confirm all php sessions are set ok. Even my site’s other things are working ok. Except CAPCHA.
I modified .htaccess file by appending the code below.
<Files *.php>
allow from all
</Files>
But no luck. My .htaccess is located in public_html folder.
I have done some comparison test with my development server and public server. By typing URL on address bar
1) Public server : – https://www.greentank.co.nz/wp-content/plugins/si-contact-form/captcha/securimage_show.php -> showing Page not found (404)
However while typing
2) Development server : – https://www.greentank.des/wp-content/plugins/si-contact-form/captcha/securimage_show.php -> Showing CAPCHA image. Also if I refresh the page different CAPCHA image also appear seamlessly.
Please Note: There is 1:1 site transfer from Development server to public hosting.

What WordPress version are you running in your development server? What PHP version are you running in the development version in comparison to the plublic version?

Hi mbrsolution
Thanks for your response
My development server is as follows
OS= Ubuntu server version 14.04.3 LTS
Wordpress version = 4.4
PHP version = 5.5.9
Mysql version = 5.5.46

Sorry forgot to ask you…. Can you provide the same information as above for the live server? Just trying to see what are the differences.

My hosting provider is Crazy Domains.
PHP version was = 5.4
Now I have changed to 5.5.
But still no luck.

What sort of information do you want?

I have asked my provider about OS. But call center could not be able to say about OS.

This is the Error log
[Tue Dec 15 08:54:26 2015] [error] [client XXX.XXX.XX.XX] SoftException in Application.cpp:261: File “/home8/greentan/public_html/wp-content/plugins/si-contact-form/captcha/securimage_show.php” is writeable by group, referer: https://www.greentank.co.nz/get-in-touch/

Could it be a file permission issue? I am wondering …..
