Hi hawkeyentjc,
For the 1st point:
Go in Hikashop > Display > Views and edit the view: "mini.php" in the frontend.
For the line:
(<?php echo $hikashop_vote_average_score.'/'.$hikashop_vote_nb_star; ?>)
Add the "round()" function like that:
(<?php echo round($hikashop_vote_average_score,2).'/'.$hikashop_vote_nb_star; ?>)
And for the second point:
Edit the file: YourSite\components\com_hikashop\views\vote\view.html.php
Delete the lines:
if ($hikashop_vote_average_score == 0){
$hikashop_vote_average_score = $hikashop_vote_nb_star / 2;
}
in the function mini and form.
