Hi,

thanks for the information!!

I fear that is a problem due to Visforms.
I will check into this as soon as possible and if necessary provide a bugfix.
I was told, that recaptcha 1 still works and there is the Visforms captcha as an alternative, too as a workaround, until I can tell you whether this is due to visforms or not and provide a bugfix if it is cause by Visforms.

Hi,

well I should have used the Jooma! JCaptcha class to include the repcaptcha in the form.
But, as I did not, Visforms is not able to handle Recaptcha V2.0 properly.
You can change this relatively easily.
Open the file administrator/components/com_visforms/helpers/html/visforms.php
There is a function getCaptchaHtml
Find the code lines
else if ($form->captcha == 2) 
                {
                    JPluginHelper::importPlugin('captcha');
                    $dispatcher = JDispatcher::getInstance();
                    $dispatcher->trigger('onInit','dynamic_recaptcha_1');
                    $html .= '<div id="dynamic_recaptcha_1"></div>';
                }
in this function and replace it with
else if ($form->captcha == 2) 
                {
                    $captcha = JCaptcha::getInstance('recaptcha');
                    $html .= $captcha->display(null, 'dynamic_recaptcha_1', 'required');
                }
I had to generate new Recaptacha 2.0 compatible keys as well but after that and clearing all browser caches, the V2 Recaptcha was displayed properly and work fine.
Please let me know, if this fixes the problem. I could merge thechanges into the Visforms code then and (after waiting a bit longer if any other issues with Joomla! 3.5 pop up) can release a bugfix version of Visforms.

Aicha

Hi,

thanks for the response!

I will insert it for sure in Visforms 3.7.1 (beta).
I think I will release a stable Visforms 3.6.11 with this fix to, but only after I have waited a bit longer, if there comes up other problems with Joomla! 3.5 so that I can make one release for all problems cause by the update of Joomla! 3.5.
