how to hide login,register buttons after logged into wordpress

Can you please be a little bit more specific about what buttons you are referring to?

Do you use the short code or the sidebar widget?

What “short code to edit the plugin” do you mean? I know of no such code?

Hi ,

Sorry for the confusion , what i meant was , before logging in my website they can see this tabs such as “Register” and “Login” But after i logged in to site , “register” no longer appear , and “Login” turns into “Logout” .

Do you understand now ? ??

Thanks !
