Plugins do not automatically load js/css

First of all, this is a great plugin, I like it very much and can’t leave it. Some recent problems have prevented me from using them properly.

Recently I used cached output for the content of the article, and the plugin no longer works.

The plugin segment code can output the code normally, but the CSS/JS file cannot be loaded automatically.

If I click on the preview change in the article editing page, the article in preview mode can load the file normally.

This made me very confused, I tried to read the code of the plugin loading file part, but still can’t understand why.

Below is the code for my cached article.

$group = 'single';
    if(is_user_logged_in()){
        $key = 'login'.get_the_ID();
    } else {
        $key = 'tourist'.get_the_ID();
    }
    if(is_preview()){
        $html = false;
    } else {
        $html = zww_cache_html($key, $group);
    }
    if(! $html){
        ob_start();
......Article content......
 $html = ob_get_clean();
    $html .= "<!-- From single_post cache in ". date("Y-m-d H:i:s",time())." -->";
    zww_cache_html($key, $group, $html, 86400);
    }
    echo $html;
