Uhm, my last thread was closed:
https://stackideas.com/forums/remove-login-register-box-in-easysocial but not solved yet. I just answered Arlex question and was waiting for an answer.
Problem is, I wanted to remove the login box and therefor have mini registration inside the sidebar. I cleared the content of the file /components/com_easysocial/themes/wireframe/helpers/html/login.php and the login box disappeared but inside my mini registration the recaptcha is not working yet. I think it is still loaded somewhere else related to that login box...
