I have Joomla! installed on my site and have the jpf chat plugin enabled. It worked fine yesterday, but today I am getting the error:

phpFreeChat cannot be initialized, please correct these errors:
filemtime php fuction is not usable on your filesystem. Please do not use the 'file' container (try the 'mysql' container) or swith to another filesystem type.
What's up?
