How did you fix it?

I want to do the same thing with my site, i.e run it on https behind nginx proxy.
Could you please post the complete nginx config file for your blog?

I also need this, will be great if it lets the user put a pin on his location also

The plugin expects to give it also the port number, that is why it is not working with unix sockets which does not use ports, so I set it like this:
/tmp/memcached.sock:0
and it seems that it is working for me and the error is disappeared now.

Why this is tagged as “resolved”, I am getting the same error and no fix here!

I am also getting the same error in one of my sites and it did not work (on ubuntu 13.10 and php 5.5.3). But it is working perfectly in my other site (on ubuntu 14.04 andphp 5.5.9),

great

I just downloaded V1.7 and I think you still did not fix the COLLATATION problem, I thinks you should add the collate and charset in your sql. See how WordPress does that in its function wp_get_schema:

Thanks.

That is great. Many thanks.

Was this fixed in the new 1.7 release?

I have fixed that by replacing you line:

add_filter('register_post', array(&$this, 'obr_register_validate_answer'), 10, 2);

by this line

add_filter(‘registration_errors’, array(&$this,’my_validate_answer’), 10, 3);

and added this function:

function my_validate_answer($errors, $sanitized_user_login, $user_email) {

                if (!session_id()){
                        session_start();
                }
                if ((!isset($_POST['answer'])) || ($_POST['answer'] == '')){
                        $errors->add('obr_error',__('Error: please fill the required field (humancaptcha).', 'humancaptcha'));
                }
                $user_answer = md5(strtolower(trim($_POST['answer'])));
                $obr_answer = strtolower(trim($_SESSION['obr_answer']));
                if ($user_answer != $obr_answer){
                        $errors->add('obr_error',__('Error: your answer to the humancaptcha question is incorrect.', 'humancaptcha'));
                }

Yes it did solve the problem, using mysql i executed the query:
alter table wp_obr_humancaptcha_qanda convert to character set utf8 collate utf8_general_ci;

Many thanks.

I added the question :
???? ????????: ???? ? ???? ? ?????
and the answer

and clicked on “Add New Q & A”, the question became:
???? ????????: ???? ? ???? ? ?????
It also appears like that in the signup page.

I am using WordPress 3.9.1 Arabic and HumanCaptcha 1.6
