MyCred on profile page in front-end

Hello,

searching in the forums i found this code to add mycred points balance in the profile page under the joined date.

<?php echo ‘My Points: ‘.do_shortcode( ‘[mycred_my_balance]’ ); ?>
<?php echo ‘Points’.do_shortcode( ‘[mycred_my_balance type=”mycred_default”]’ ); ?>

But actually it’s not working and the page gives me back a 500 error.
If can be useful i’m using php 7.1, may be for this reason ?
