Documentation > CometChat PHP > Frequently Asked Questions > How can I hide past messages when a user joins a chatroom?

Whenever the user joins the chatroom he/she can view past messages which help him/her understand what is being discussed.

However you can change the number of last messages to be displayed through CometChat Admin Panel:

1. Login to your CometChat Admin Panel ->Modules Tab-> Click on “Configure module” button for the Chatrooms

2. Set “The number of past messages that will be displayed on joining a chatroom.”

No_of_last_message

Note that the minimum value that must be set is 1. It cannot be set to 0.
