The Sj Contact Ajax stopped working properly on my site and I see your demo site for the module is showing the same symptoms - it doesn't stop (demo.smartaddons.com/extensions/joomla3/index.php/other-extensions/sj-contact-ajax)

I tried changing from custom to reCaptcha, it sends the mail but is still rolling this circle on the site - and the "send copy to yourself" doesn't work, i.e. the mail doesn't arrive.

Dear sir,
Could you please feel free to post your question into our ticket system? We need more detail your information to check.

Thanks.

I am also facing same issue for my site www.hrlingua.com. I have made a request through support ticket but I am yet to receive any response.

Hi

I think it's starting at the wrong end to try to fix my site, I think you need to get your online demo working properly, see link above.

I found another contact form that worked right from the start without any issues and I will be using that till your demo is working.

Dear sir,
Please check ticket, we replied your ticket.

Thanks.

I think you should let us know what your answer to his ticket because I think I've got the same issue. When I click on submit, the loader still rolling and never send the email even if I change captcha custom to ReCaptcha or I disable it.
