I have created a responsive Bootstrap based theme for the clients section of osTicket. This gives the clients a better visual and functional experience when compared to the default setup. The layout is fully responsive that enables effective usage on mobile devices. The ticket admin section is not customized . The theme has customizable logo, customizable hero section on the homepage, social media icons of the footer etc. This theme gives a complete makeover to the client section of your support ticket system. The customization is compatible with the latest 1.9.5 version of osTicket.
