There has been a critical error on your website.

I modified the above code as per my requirement and put it in function.php
please check it this method is correct

Did you expand the code block and copy/paste exactly as given?

Please put the code here that you attempted to use. Make sure to surround any code you paste here in code tags.

Hi,
please find the code below

The code you pasted does not cause any critical errors (or any other errors) on my website.

If you are putting this inside your theme’s functions.php file, make sure the PHP file begins with <?php

Hi,
It is working but not showing the correct value of rating in my case it is taking the last criterion rating as overall rating.However i was looking average rating of individual criterion and overall rating of all criterion.

1. In order for the review rating to reflect the overall rating of your custom rating fields, you need to make sure to hide the rating field in the form as explain here: https://www.ads-software.com/support/topic/multi-set-reviews/#post-12350061

2. The summary will only show the average rating of the main review rating. It is not possible to show the average rating of custom fields in the summary shortcode.
