Fatal error: Uncaught Error: Class 'BBP_BuddyPress_Activity' not found

[jasonrush]

WordPress version: 5.7
bbPress Version 2.6.6

Client wanted to disable the activity stream, went to Dashboard > Settings > BuddyPress > Components > Activity Streams and Unticked the option. When he hit save it said There has been a critical error on this website and the entire website (including admin dashboard) was unreachable/unusable (only returning this error).

After enabling debugging info, I received the following error (paths sanitized for security):

Fatal error: Uncaught Error: Class 'BBP_BuddyPress_Activity' not found in public_html/wp-content/plugins/bbpress/includes/extend/buddypress/loader.php:153 Stack trace:
#0 public_html/wp-includes/class-wp-hook.php(292): BBP_Forums_Component->setup_components('')

#8 public_html/wp-co in public_html/wp-content/plugins/bbpress/includes/extend/buddypress/loader.php on line 153

I was able to temporarily resolve the issue by patching the following function (wp-content/plugins/bbpress/includes/extend/buddypress/loader.php):

Line 153 being the "new BBP_BuddyPress_Activity()" line.

        /**
         * Instantiate classes for BuddyPress integration
         *
         * @since 2.0.0 bbPress (r3395)
         */
        public function setup_components() {

                // Always load the members component
                bbpress()->extend->buddypress->members = new BBP_BuddyPress_Members();

                // Create new activity class
                if ( bp_is_active( 'activity' ) ) {
                        bbpress()->extend->buddypress->activity = new BBP_BuddyPress_Activity();
                }

                // Register the group extension only if groups are active
                if ( bbp_is_group_forums_active() && bp_is_active( 'groups' ) ) {
                        bp_register_group_extension( 'BBP_Forums_Group_Extension' );
                }
        }

Patched code:

                // Create new activity class
                if ( bp_is_active( 'activity' ) ) {
// Temporary patch!
if ( ! class_exists( 'BBP_BuddyPress_Activity' ) ){
require_once(dirname(__FILE__).'/activity.php');
}
                        bbpress()->extend->buddypress->activity = new BBP_BuddyPress_Activity();
                }

Let me know if there's any additional information that would be helpful.

Hey @jasonrush thanks for creating this ticket. I've corrected the formatting and deleted your correction comment, just to keep everything tidy.

Your recommended code change will prevent the error from making it to the screen, but I think correcting the error needs to happen earlier to make sure the file is always loaded when it needs to be.

What version of BuddyPress are you using, and how do you have it activated (single-site, multi-site, network active, etc...)

I wasn't able to replicate on single-site. I don't have a multisite install to test with right now, but I can set one up soon.

The error message you're seeing technically shouldn't be possible.

• bbp_setup_buddypress is hooked to bp_include like BuddyPress components are
• BBP_Forums_Component::includes() uses bp_is_active( 'activity' )
• BBP_Forums_Component::setup_components() uses bp_is_active( 'activity' )

The only thing I can imagine is some kind of race condition with updating the buddypress()->active_components array, maybe related to a cache invalidation, or a broken redirect.

Thank you again, and talk soon!

I figured this was probably not the best way to patch, but had to find an immediate solution to the issue for the live site and figured I'd pass it along as an added data point. I'm all for finding the proper solution. This site is on a single-site instance of WordPress. It's definitely possible it could be a race condition (there are several BuddyPress related plugins installed), but I believe I did clear cache in troubleshooting so while I'm not certain I'm doubting it's a caching issue. As for a broken redirect, as it seems to be a PHP include issue, I'm not sure how that would involve redirects, though I'm not particularly familiar with the BuddyPress or bbPress codebases.
