Ok so I ran the install. I read the other post and it's still unclear to me if this is working.
I am using stella theme. at the bottom it says I might have to install code after form.
It says I should see a identification in the btm corner if it is working but I don't see anything.
I have this in my contact.php


         <div class="req-what"><div class="req">*</div><div class="small-info"><?php _e('This field is required', 'stela'); ?></div></div>

          <?php stela_show_recaptcha(); ?>

          <button type="submit" id="blue"><?php _e('Send message', 'stela'); ?></button>
        </fieldset>
        </form>
      </div>
    </div>

am. I supposed to install the line here?

You replace following code:
stela_show_recaptcha

with one from plugin.

cannot contact ReCaptcha check your connection and try again

?   any hints

I ment to say how appricative I am of your response. Very timely. I think osclasspoint gonna kill the competition
Keep up the great development work, I will be a supporter one plug-in at a time

The strangest thing is happening.
with the plug-in installed and a change is made to the settings a box drops down to confirm password change
after this happens I can no longer log-in to my site as admin. This has happened several times. I have to go to my control panel and delete the plugin in order to log in as admin

I returned to the v2 ReCaptcha and it works again

This happened to me as well, when I've checked to protect oc-admin login form, but did not update this form. Each attempt then result in failed recaptcha.

I use the ZARA Theme (This works fine, but the spammer...)
Now I have the plugin invisible ReCaptcha installed and enter the two google keys. ok.

Then have "Registration Form Enabled" active. 
"ReCaptcha will be added to registration form. No theme modifications are required"!!!!!

When start my page with this contact form -->  eCAPTCHA can not be reached. Please check the connection and try again....

What can i do now???

@matmatsen

Dear, I am using the issue starter theme and I have problems of invisible captcha, it will be something that I am doing wrong, create again invisible captcha but the error continues

Well, you've not added your domain into allowed domain list in google api settings.

Dear, I request your help please, I have tried in several ways, but I can not make the invisible captcha work, the error message keeps coming up, what can I be doing wrong? the domain is verified by google

Use starter, the theme already has the invisible integrated or you have to add the code in the different files

add the line in  user-register.php and it is not <form> only </ form>, I wait more than an hour but everything remains the same


Following code must be placed after <form> attribute:
<?php osc_run_hook('invisible_recaptcha'); ?>

It's not error from plugin, but from recaptcha service.

Dear:
After several hours lost I found the error (I think)
there is a key that does not correspond, when changing it by my key it works, so if there is a code error (I'm not a programmer, I'm just a good observer)

functions.php

Dear I am presented with another problem, when Admin Login Form Enabled is active, you can not enter the control panel once it is exited, you can enter login and pass but it does not recognize them, nor does it give an error message, nor can you see that there is the active captcha

Thanks for your feedback.
Please update to v1.0.3, problem with keys should be resolved.

Temporary we have disabled captcha on admin login as there are few complications and it require modification of oc-admin files in order to make it work.
