hi
sorry for the delay in reply
if you want to redirect the user directly to your custom login login page then
Try this code in Go to wp-admin > WPLMS > Footer > Google Analytics Code add the code with the script tag and save changes.
<script>
jQuery(document).ready(function(){
jQuery('.logged-out a.vbplogin').on('click',function(event){
event.preventDefault();
event.stopPropagation();
window.location = 'www.google.com';
});
});
</script>
www.google.com : change this with your custom login/ registration link.
Good luck.
