My original answer was all wrong, so it’s been removed in it’s entirety. Neither the posts_selection nor wp hook are fired during the REST API request. The hook you need is rest_pre_echo_response. This hook passes three parameters: The response data to send to the client The server instance. The request used to generate the response. … Read more
OK, so your first problem is that $current_user->roles is an array and not a string, so your condition won’t be true 😉 My another concern would be the hook you’re using. Some plugins may use it for other purposes, and killing the script can be harmful. And… there is much better hook for this 😉 … Read more
To see if the option ‘rewrite_rules’ was reset – that’s what flush_rewrite_rules() does internally – hook into the option actions and log what happens. The following small plugin does that.

comment_post hook pass to attached functions 3 parameters.

If that class works as a singleton and has a getInstance() method (or similar) to retrieve the instance, you can remove the action pretty much the same way it was added: remove_action(‘wp_travel_engine_enquiry_form’, array( $instance, ‘wpte_enquiry_form’ )); Edit: I’ve looked into this some more, and you find the necessary information by looking into $wp_filters (global variable, … Read more
The issue for me was the clean_script_tag() function from Soil. Removing add_filter(‘script_loader_tag’, ‘clean_script_tag’); solved the bug for me.
