Hi we’re having a similar issue to this.
We’re using a custom theme and so I’ve added the php snippet where I want it, which is separate from the content body.
The issue I’ve come across is if we tick “Enable WP Customer Reviews for this page” then the reviews also display at the bottom of the main content area. Unfortunately, if I leave the enable button un-ticked then when a review is added, the post id gets overridden when the review is accepted because $this->get_all_posts_pages(true);
(line 614 of wp-customer-reviews-3-admin.php) only gets the enabled posts.
I also can’t trust my authors not to tick enable if I hacked my way around that bit!
If you have a public git repo I’d happily fork and provide a pull request to fix this.
Thanks
Nathan Edwards
