After upgrading to WPtouch Pro 4.x, you may notice a "Login" link in the WPtouch Pro header menu. If you would like to remove it, it can be done with the CSS code below. 


.login-link {
display: none !important;


Add the CSS code in Appearance > Customize > Custom CSS. Additional information on applying CSS to WPtouch Pro can be found here - Adding custom styling to your WPtouch Pro theme.
