West Ham captain Mark Noble is urging fans to end the rage.
Issues with stewarding and seating have also caused problems at the new London Stadium and the club are in talks with the owners of the ground over numerous points of action.
Noble said: “Forget about the football. You think about young kids seeing what's been going on in the stadium and it isn't really right.
“I wanted to send this message. We really need the fans to get behind us now rather than fighting among themselves. We're a family. It's not us and them. We need to be all together.
“But you have to understand – and as a West Ham fan I do – where the fans are coming from. If a family of five go with three children we need them but we also need the geezer standing up in front of them. That's the problem right now.
“If a person pays good money for a seat and wants to stand up and cheer and then has an 18-year-old steward telling him to sit down you ask any West Ham fan and ask them what they're going to say, it isn't going to be nice but that's the problem we've got.
“We need to come together and the board are doing their best to sort this out and get the fans behind us. It will get better."
