Multisite Chat won't save settings.

I keep getting this message on all of my subsites:

You have installed the WordPress Chat plugin. Please review the polling interval settings before using. In most cases the default options will work for your host configuration. However, in some unique cases the polling interval is too frequent and could cause your hosting to shutdown your account. Once you have reviewed and saved the chat settings this message will no longer appear.

I have gone to the settings and saved them multiple times. The message goes away until I revisit the dashboard of each subsite. What am I missing here? I have Chat network enabled.
