BuddyPress.org

Hello, Greetings to all:
I am trying to create a new social network thanks to this plugin. It was working correctly in my multisite installation on blog 1.
Due to the great load of this blog we decided to transfer the social network to a secondary blog.
A collaborator now disappeared was in charge of transferring all the contents, and comments to the secondary topic and everything seemed to work well.
However, we have noticed that all network updates are identified with the same id. and comments are now saved as p/0.
The cid variable is not being saved correctly
Could you help me solve this problem?
Thank you very much in advance.
