I am running Cimy User Extra Fields v2.5.0 on a WordPress MS setup, and I'm using the securimage captcha.
The captcha is shown correctly & works properly on the public user registration form, but the Add User option in the dashboard was also getting blocked by the captcha (the actual captcha not being shown). I had updated from 2.4 to 2.5 of the plugin to see if that fixed it, but it didn't.
I ended up updating
cimy_uef_register.php at line 625 (the cimy_registration_captcha_check function's conditional statement for giving certain forms a pass on the captcha) so that it excludes the admin forms from the captcha check.
It was changed from:
if (!empty($_POST['register_confirmation']) && ($_POST['register_confirmation'] == 2) && (wp_verify_nonce($_REQUEST['confirm_form_nonce'], 'confirm_form')))
if ((!empty($_POST['register_confirmation']) && ($_POST['register_confirmation'] == 2) && (wp_verify_nonce($_REQUEST['confirm_form_nonce'], 'confirm_form'))) || (!empty($_POST['_wpnonce_create-user']) || !empty($_POST['_wpnonce_add-user'])))
This is a hack that works for me, and I thought I should report this in case anyone else is experiencing this issue, or if you know of a better fix for this.
As an aside, the network admin's add new user form is also getting caught by the extra fields that were marked as required (ex. "ERROR: First name couldn’t be empty." when that field isn't shown in that form). This might be related as it's an issue with form validation within the site admin, but I got the most pressing issue solved with the hack shown above.
Any input/feedback would be greatly appreciated. Thanks!
