I have take a look buddypress new version 2.9.4 that has file/folder structure changed.
What I have done is that I replace bp-members and bp-core folders with new versions folder.
I also replaced bp-loader.php and upload class-buddypress.php file to the root of buddypress plugin and then updated wordpress core to the latest version. it worked successfully.
But I don’t want this. I simply want wordpress core update without updating/editing buddypress plugin files/folders.
Can you please tell me that why this error comes so that I can research on that. Am I missing something or anything you may advice.
Your remark: It could well be that your own mods to BP Core have caused this
My remark: Can you explain or hint on this so that I can turn it off or do any custom coding to fix it.
