How to change the widget height

it’s easy to change the widget height via css. Just insert the following (adjust the height to whatever you like):
#sb_messages {
height: 600px;
You can either put this to your theme CSS, or if you are using a standard theme, then maybe putting this to Jetpack → Custom CSS is better place (so it is not overwritten once you update the theme).



there is no better chat plugin than this one. try to find out and see. lepší pluging na chat nenajdete. věřte mi.

Great way to get hacked

The sanitizing and security in this plugin make it dangerous as hell... Designer/Developer be warned, Out of the box this code isn't production ready.
