Brilliant!! I replaced the bp-members-membership-requests.php with the version you provided and no more fatal errors. Thank you.

I disabled all the plugins and switched the theme to twenty-twenty-two. There is no bp-custom.php file. I also downloaded the latest version of BuddyPress and replaced the original BP 10.3.0 plugin folder with the newly downloaded one. I am running PHP 7.4.

The same fatal error persists while the user requesting site access gets approved.

Here is the fatal error from the error screen:
Fatal error: Uncaught Error: Class ‘BP_Notifications_Notification’ not found in /home/nondualhealersas/public_html/wp-content/plugins/buddypress/bp-members/bp-members-membership-requests.php:249 Stack trace: #0 /home/nondualhealersas/public_html/wp-includes/class-wp-hook.php(309): bp_members_membership_requests_delete_notifications_on_change(Array) #1 /home/nondualhealersas/public_html/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(false, Array) #2 /home/nondualhealersas/public_html/wp-includes/plugin.php(476): WP_Hook->do_action(Array) #3 /home/nondualhealersas/public_html/wp-content/plugins/buddypress/bp-members/classes/class-bp-signup.php(961): do_action(‘bp_core_signup_…’, Array, Array) #4 /home/nondualhealersas/public_html/wp-content/plugins/buddypress/bp-members/classes/class-bp-members-admin.php(1816): BP_Signup::activate(Array) #5 /home/nondualhealersas/public_html/wp-includes/class-wp-hook.php(307): BP_Members_Admin->signups_admin_load(”) #6 /home/nondualhealersas/public_html/wp-includes/class-wp-h in /home/nondualhealersas/public_html/wp-content/plugins/buddypress/bp-members/bp-members-membership-requests.php on line 249

Also, from WordPress’s built-in fatal error detection feature:

WordPress version 6.0.1
Active theme: Twenty Twenty-Two (version 1.2)
Current plugin: BuddyPress (version 10.3.0)
PHP version 7.4.30

In addition, the only other BP plugin I had been using was BuddyPress Xprofile Custom Field Types Version 1.2.4 by BuddyDev. This has been disabled along with everything other than the BP plugin so I’m not sure if this has any relevance.

Assistance would be appreciated.
