 * Good afternoon,
 * WP 5.4
    Theme Bridge + Woocommerce / WP Rocket
 * I search some solution with the next problem.
 * We use Query Monitor which appear many times when we delete or update one post/
   page. Also we can’t check the preview of some page (Blog or draft, for exemple):
 * The message above was triggered by Core.
 * Call stack:
 * 1. wp_die()
    wp-includes/revision.php:595
 * 2. _show_post_preview()
    wp-includes/class-wp-hook.php:287
 * 3. do_action(‘init’)
    wp-settings.php:540
 * I don’t understand what I can do in this situation.
 * Thank you
    Regards

 * Going to be very difficult to diagnose with looking and code and testing.
 * Unfortunately, you’ll have to look at each file in the call stack, on the line
   specified, and try to see what is happening…
 * Try deactivating plugins, one by one and see if that resolves it (to find which
   plugin is causing issues)

 * Try advanced debugging:
