recaptcha HTML code is rendered but block not visible (4 posts)

    I checked it is not plugin conflict by disabling all other plugins. It was working fine before my site goes live. Now that the website is live and people try to register, they cant see the captcha block and get error on form submit "ERROR: Invalid reCAPTCHA challenge parameter.".

    My keys are correct. This is very frustrating as I cant find where is the root of the problem. I check firebug DOM panel and can see the public key.

    Please any help appreciated.

    Looks like an external conection problem. Try with a simple test with fget() or file_get_contents() function and this help to you looks if your hosting is able to outside conections.

    Our plugins use outside conections too (more speficly "fopen()"), try setup it and your account will be generated automatically. If works, your hosting it's ok, but your config of reCAPTCHA plugin is wrong.

    The Plugin page is:

    Not necessary.

    This is a PHP test wich help to you understand what functions found in your hosting:


    Here is the Virustotal scan: https://www.virustotal.com/es/file/852f764c9889c773443f76946c6d65b56fde79192729ec2ab840aee8ad6871c3/analysis/1378665763/

    So, when you know what functions found in your server thats allows you start to view what is the problem. Sometimes happens (in my experience since I'm captcha provider) in the hosting manage team view multiply outside and inside connections and without any research block with the firewall the connections. Thats literally "kills" the captcha system.

    So to solve it do you need to test the external connections or too try to ask with your hosting support if they have change something rule on your server / firewall.
