Hi,

I'm curious if anyone has found a way to use the functions.php file in a child theme to remove the WPDiscuz CSs styling from the head. Those settings never change and I want to load them from within my custom external stylesheet that is loaded only on single post pages instead of within the HTML. I've found a function called InitCustomCSS while looking through the plugin files in my cPanel, but I cannot figure out how to remove that action from the wp_head, which I assume the function is hooking into to add styling to the head. If anyone has figured out a way to remove WPDiscuz's styling from the head section that'd be terrific.

Hi  lostnotstranded,

I'm really sorry, but there is no any way to do it. We'll take it into consideration for future releases.

I stumbled over this thread while searching for a solution for this problem.

To solve it I now iterate over the "wp_head" callbacks and search the right one to remove it:

function remove_wpdiscuz_custom_css()
{
    global $wp_filter;

    $priority = 10;
    $hooks = $wp_filter['wp_head']->callbacks[$priority];
    foreach ($hooks as $hook) {
        if (isset($hook['function'][0]) && $hook['function'][0] instanceof WpdiscuzCss && $hook['function'][1] == 'initCustomCss') {
            remove_action('wp_head', $hook['function'], $priority);
            break;
        }
    }
}

add_action('wp_head', 'remove_wpdiscuz_custom_css', 8);

@mirsch

I followed your suggestion and Query Monitor is showing that the hook is no longer registered inside wp_head, and yet... the inline CSS gets printed inside my document head regardless.

(no i'm not using a caching plugin)

Has anyone figured out how to stop initCustomCss from firing? Is the plugin doubling down on the method somewhere else?

@luboslives,

We've just checked on our test website and don't find such an issue. Everything works fine.
Could you please check one more time.

I've figured it out – I missed a small detail! I didn't realize @mirsch was using a hook priority of 8. I had it at 10 in my theme functions file. It might seem counterintuitive in a way, but it needs to have a higher priority than the initCustomCss hook so that it can deregister it before it's executed by WordPress.

I guess Query Monitor can't figure out whether something actually executed before being removed by a function that happens to have the same priority.
