Please firstly ensure you are using the latest version of the Shoutbox available. If you get any errors after updating, it might be due to a template override, so try backing the file up and deleting it.
In the Pro version (v11 and above), we use CSS variables to determine the colours:
Assuming your template supports a user.css file, you can change the colours by simply overriding a variable, like so:
The Shoutbox is Ajax driven. It does not use websockets for a live feed, therefore each time you submit, delete, edit, update, 'thumbs-up' a shout or the Shoutbox is refreshed, this submits a request to the server.
Some hosting providers limit the amount of requests allowed per hour, day, etc. If you noticed too many resources are being used due to the Shoutbox, you can do any of the following:
Can edit own shout?
Can delete own shout?
Auto refresh for guests
To prevent spam, disabling the Shoutbox for guests would be a good place to start, but if you require the Shoutbox for public use, then please enable one of the spam prevention features (we suggest ReCaptcha).
If you're being spammed by a specific user, the Pro version of the Shoutbox has an IP ban feature which will come in handy.
When a major update or feature is due to be rolled out, we sometimes release a Beta version of the Shoutbox. This is clearly marked on the Download page, so please remember that it should not be used for production websites. If you would like to test it, please feel free and any bugs or suggestions should be submitted to out Github Issue Tracker
