Do it just like AnsPress adds all other tabs. Look in sources: ap_register_user_page( 'about', __( 'About', 'ap' ), array( $this, 'about_page' ) ); ap_register_user_page( 'activity-feed', __( 'Activity Feed', 'ap' ), array( $this, 'feed_page' ), true ); ap_register_user_page( 'notification', __( 'Notification', 'ap' ), array( $this, 'notification_page' ), true, false ); ap_register_user_page( 'profile', __( 'Profile', 'ap' ), array( $this, 'profile_page' ), true, false ); ap_register_user_page( 'questions', __( 'Questions', 'ap' ), array( $this, 'questions_page' ) ); ap_register_user_page( 'answers', __( 'Answers', 'ap' ), array( $this, 'answers_page' ) ); ap_register_user_page( 'followers', __( 'Followers', 'ap' ), array( $this, 'followers_page' ) ); ap_register_user_page( 'following', __( 'Following', 'ap' ), array( $this, 'following_page' ) );

If there is no category, then category fields will be hidden. But user can add new tag if that doesn’t appear in tags suggestion.

Yes, there are option for you need. Check in wp-admin->anspress->options

I agree with @Dima. There is no need of additional like system. You can easily turn voting button to like button. There is an option in AnsPress to hide down vote, do it and add some CSS.

.ap-q-inner .ap-post-history { display: none; }

You would need to write custom PHP code to achieve this. It will be pretty simple, just mimic the upvotes logic. (are you sure you want to add another likes system? there is already “likes” and “dislikes”, the thumbsup and thumbsdown icons near the number)

var_dump(ap_post_votes(ap_question_get_the_ID()));

I have upgrade my php to PHP Version 5.6.15 and now it`s ok

Just spend a few minutes to review the options. In Anspress admin / Options / Moderate. It is SO evident !!

This issue has been reported already and I am trying to find the issue.Is there any error in your log?
