Hello,
I'm sorry but this is an issue with Google Chrome and the AJAX Chat MOD.
It is fixable on
Advanced Hosting (by uninstalling that version and installing a different one) but unfortunately we won't be applying a fix to it because the current chat features are due to be removed from the system and replaced by a 3rd party chat program.
I apologize for the inconvenience and thank you for your patience and understanding - in the meantime, if you have any more questions please don't hesitate to ask and we'll be happy to help
