    Hi,
    I’m having this problem. All my cache is cleared when a user log into the web. Is there any wp hook that I have to unable?
    This is my config:
    mod_rewrite + compress + don’t cache known users + mobiles + 3600 expritaion date

  • It shouldn’t do that. Have you tried using the debug system in the plugin to track down what the problem may be?

    Resolved,
    It is Buddypress that clear all cache when an user login,
    the solution, remove the filter, put it into your functions.php:

    remove_action('wp_login', 'bp_core_clear_cache');

    Bizarre. It looks like a drastic action to take but the original code is here.

    hi javiarques/Donna,

    Could you tell me in more detail ?
    functions.php is it located under ‘wp-includes’ ? or under theme files ?
    in functions.php where exactly I need to add this remove_action ?

    Hi mmln,
    You just have to insert the line
    remove_action('wp_login', 'bp_core_clear_cache');
    in your functions.php located in your theme. And if you dont’t have it, just create it, and it will be called by WP.

    This is the function created in Buddypress plugin

    /**
     * bp_core_clear_cache()
     * REQUIRES WP-SUPER-CACHE
     *
     * When wp-super-cache is installed this function will clear cached pages
     * so that success/error messages are not cached, or time sensitive content.
     *
     * @package BuddyPress Core
     */
    function bp_core_clear_cache() {
    
    	global $cache_path, $cache_filename;
    
    	if ( function_exists( 'prune_super_cache' ) ) {
    		do_action( 'bp_core_clear_cache' );
    
    		return prune_super_cache( $cache_path, true );
    	}
    }

    This function is called tons of times!!!!, and that’s an extreme solution for my huge portal el embarazo .net, with more than 3000 cached posts, and 20.000 users:

    // List actions to clear super cached pages on, if super cache is installed
    add_action( 'bp_blogs_remove_data_for_blog', 'bp_core_clear_cache' );
    add_action( 'bp_blogs_remove_comment', 'bp_core_clear_cache' );
    add_action( 'bp_blogs_remove_post', 'bp_core_clear_cache' );
    add_action( 'bp_blogs_remove_blog_for_user', 'bp_core_clear_cache' );

    add_action( 'bp_blogs_new_blog', 'bp_core_clear_cache' );
    add_action( 'bp_blogs_remove_data', 'bp_core_clear_cache' );
    
    add_action( 'wp_login', 'bp_core_clear_cache' );

    add_action( 'friends_friendship_requested', 'bp_core_clear_cache' );
    
    add_action( 'groups_join_group', 'bp_core_clear_cache' );

    add_action( 'groups_premote_member', 'bp_core_clear_cache' );
    add_action( 'groups_membership_rejected', 'bp_core_clear_cache' );
    add_action( 'groups_membership_accepted', 'bp_core_clear_cache' );
    add_action( 'groups_membership_requested', 'bp_core_clear_cache' );
    add_action( 'groups_create_group_step_complete', 'bp_core_clear_cache' );
    add_action( 'groups_created_group', 'bp_core_clear_cache' );
    add_action( 'groups_group_avatar_updated', 'bp_core_clear_cache' );
    
    add_action( 'messages_delete_thread', 'bp_core_clear_cache' );
    add_action( 'messages_send_notice', 'bp_core_clear_cache' );
    add_action( 'messages_message_sent', 'bp_core_clear_cache' );
    
    // Don't cache message inbox/sentbox/compose as it's too problematic
    add_action( 'messages_screen_compose', 'bp_core_clear_cache' );
    add_action( 'messages_screen_sentbox', 'bp_core_clear_cache' );
    add_action( 'messages_screen_inbox', 'bp_core_clear_cache' );

    Y prefer, rather than clearing cache, do not store community pages into my cache.

    And I have modified bp_core_clear_cache and now do nothing.

    /**
     * bp_core_clear_cache()
     * REQUIRES WP-SUPER-CACHE
     *
     * When wp-super-cache is installed this function will clear cached pages
     * so that success/error messages are not cached, or time sensitive content.
     *
     * @package BuddyPress Core
     */
    function bp_core_clear_cache() {
    
            return true;
    
    	global $cache_path, $cache_filename;
    
    	if ( function_exists( 'prune_super_cache' ) ) {
    		do_action( 'bp_core_clear_cache' );
    
    		return prune_super_cache( $cache_path, true );
    	}
    }

    Hi javiarques,

    I tried removing action from wp_login, it does the job but from only one ‘login’ form. As you mentioned this cache prune is called many times.

    Could you tell me the modification you did to the bp_core_clear_cache so that it does nothing ?

    Any way I am not going to cache the community pages, but just the blog posts.

    You just have to modify the bp_core_clear_cache function so that the function does nothing, just return true.
    It’s not the best solution because you have to modify a plugin file wich can be updated in the future, but I dont know a better way because there are no actions or filters to hook.

    bp-core.php line 1883

    function bp_core_clear_cache() {
    
    return true;
    }
