Plugin Conflict - Ultimate Facebook vs Join My Network

Hello,

I added the Join My Network (JMN) plugin and it was running fine. A week later, I added Ultimate Facebook and the JMN plugin stopped working. I noticed one other person had this problem in the JMN support forums.

Since the developer of JMN doesn't have access to Ult Facebook's code, I was hoping someone at WPMUDEV could troubleshoot the conflict.

Thanks,
Chris
