SpeedNetHosting

Hello, I have recently been developing a custom theme for WHMCS clien area and I discovered when I uploaded my CSS, all checkboxes disappeared. Can somebody maybe help me discover why this happened? Note: I am editing five theme, and the links to all the CSS are here: <link href="https://speednethosting.com/css/mui.min.css" rel="stylesheet" type="text/css" /> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.7/css/materialize.min.css"> <link href="http://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet"> <link type="text/css" rel="stylesheet" href="https://speednethosting.com/css/materialize.min.css" media="screen,projection"/> I put these in header.tpl in the <head> ... </head> tags, inserted before the </head> tag.
