Support » Plugin: Query Monitor » Can’t see details on front-end

  • Hi, a strange bug appeared recently on my site – while working perfectly on backend Query Monitor does not open it’s screen on frontend. It’s in WP admin bar and it is working, but when I click one of it’s menu items nothing happens. Purging cache, deactivating cache and opyimizations does not help. I am using latest WP (5.6.2).

    * Any JavaScript errors in the browser console?
    * If you view the source of the page, is QM’s big block of HTML present at the bottom?
    * Are you able to deactivate any of your other plugins or switch to a default “Twenty” theme to see if one is causing a problem?

    No JS errors in console, QM code is in the HTML.
    Also tried switching off Cloudflare rocket loader and checking through another browser (although they all are based on Chromium to some degree except Safari)
    I will try to migrate my live site to localhost and experiment there.

    @johnbillion Same here. Backend perfect, frontend still white. source code is empty, too.

    1. no JS errors
    2. no
    3. I’m able. I activated the “health check troubleshooting” with using standard template and it works. by step-to-step-activating all plugins, I found out, it’s this plugin faults: https://de.wordpress.org/plugins/sem-external-links/ – if I disable this plugin on my live view, your plugin works in my frontend.

    what can we do?

    I was finally able to find what was causing the issue – it was Edge Side Caching of Litespeed Cache. It definitely looks like a bug on their side.

    I got a reply from Litespeed devs saying that it’s a known bug – https://wordpress.org/support/topic/esi-causes-problems-with-query-monitor/#post-14185503
    I am still prone to think that the problem is on their side, but wanted to inform you anyway, maybe you can have a look into it.

    Offtopic: I can really recommend WPRocket. I moved from LiteSpeed to WPRocket, too.
