There's still some problem when Minifying CSS.
Here's a example website for you to inspect - http://www.fivestarcleaning.ie/
I will leave it like that for a while for you to take a look, will remove the plugin or switch off CSS minify after that.
At the Very bottom there's a widget 'Get in Touch'. Third phone number is a fax number which should have a fax icon by it.
The background CSS for a DIV that it sits in should be
background: url("/wp-content/uploads/fax-icon.png") no-repeat scroll 0 9px rgba(0, 0, 0, 0);
Unfortunately it gets broken by your plugin, so it is now
background: url("../../../themes/freshbiz-child//wp-content/uploads/fax-icon.png") no-repeat scroll 0 9px rgba(0, 0, 0, 0);
as you will notice.
Any advice on how to fix it until you will fix the Minify CSS option?
