Thank you Chris.
However, your solution doesn’t work for me even though the #overlay CSS is at 0.6.

The plugin javascript is adding some inline styles (that I couldn’t override via CSS) that is setting opacity to 1… :-/

same problem here.how to solve it without touching the plugin files?

Thank you Krzysztof,
I’ve tried a little bit and it seems that you got the point: if I login and click on “like”, then after I logout if I click on “unlike” I get the error message.

It means that the plugin is preventing multiple “likes” with cookies, right?

Would it be possible to make the like button not clickable in these situations?

Thank you.

I get the same error on every browser, not just IE.
Thank you for posting the fix!
It’s a pity that the plugin is not updated…

However I had to change a little bit your fix:

<script type="text/javascript">
            if(document.getElementById('recaptcha-submit-btn-area') != null)
            {
                    var sub = document.getElementById('submit');
                    document.getElementById('recaptcha-submit-btn-area').appendChild (sub);
                    document.getElementById('submit').tabIndex = 6;
                    if ( typeof _recaptcha_wordpress_savedcomment != 'undefined') {
                            document.getElementById('comment').value = _recaptcha_wordpress_savedcomment;
                    }
                    document.getElementById('recaptcha_table').style.direction = 'ltr';
            }
            </script>

Basically I’m checking if the captcha exist instead of checking if the submit button exist. Since in my website the captcha is disabled for logged-in users even if the comment form is present, so they were still receiving the error.
