Hello, One of my site's member is having issues with private conversations. He was having a conversation with another member and after a few to and fro messages, he started receiving an error message: "The following error occurred: Your content cannot be submitted. Please try again later." He says he gets this error even when he tries to start a fresh conversation with any member or while responding to a conversation that he has received. I also noticed that the posts of this member automatically go under moderation even though he does not have any such pre-moderation rules applied to his account. I believe there is some anti-spam filter being triggered, but I don't see anything in the 'Server Error' logs. He has been having this issue since a few days and I am not sure what I can do to help this member out. Any suggestions on what can be done? Thank you!
