Hayley9,

Click the button near smileys icon - if it's active you will be only able to see messages you send and those addressed to you. You must deactivate in order to see all chats again.

my chat is going out again as well tonight and keep having to refresh my page to send messages :( also the lag and game freezing incidents seem worse again tonight current server time is 1:01 and just had to refresh again just before I came to post this

Chat just vanishes for no reason at all, only leaving a few red squares where the timestamps would show. I know my chat isn't locked and this problem arose since the new update(s). This hasn't happened before, and it is really rare i ever lock chat, so i know it isnt that. I'd have to alter all of my chat settings then refresh to get it to appear again starting to get a little bit annoying
