There seems to be a problem with the chat.Only if you have a slow upload rate using FTP.
I've just updated to the latest version and I am having a similar problem as well. The chat text line tells me to 'Please wait...' but nothing happens.Also, i am unable to post any messages in the chat. I am admin, with all rights. After typing something and click submit, the entire page refreshes and nothing gets in chat.
