Remove user’s last name.

Hi Deyson,

wpDiscuz doesn't show first and lt names, it shows DisplayNames. You can set any variant if DisplayName in account settings page.

Thank you very much.  Do you know how to change the display name variant for all users instead of just one at a time?  

Thank you.  

Please backup the wp_users table and try this SQL in cPanel > phpMyAdmin > WordPress Database > SQL Tab:

UPDATE wp_users SET display_name = (SELECT meta_value FROM wp_usermeta WHERE meta_key = 'first_name' AND user_id = ID);

If your tables prefix is not wp_ , don't forget to change it.

However this also may not work if you have a plugin which dinamically change all names to First + last names. Make sure this issue doesn't come from other plugins.

Thank you, I will give this a shot.  Have an amazing day!
