    I am trying to install a plugin called Captcha and it gives me an error as shown below.

    Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, '' was given in /home/root/public_html/gifts/wp-includes/plugin.php on line 173

    Can you please help. If you dont then do you know of any captcha plugin that works well with WooCommerce plugin

    Maybe it is worth mentioning that I am getting this error message when I am post a Review on a product. The error message is displayed at the top of the Review Popup

    usually, that sort of error message would give you an idea of what file / plugin originated the error
