You could use thesource. They have patched many open Issues with every new Release and added Time-Tracking.

Try to turn on Internet Access for the Webserver. Solved the Problem for me.

correction, use only:   a:hover i[class^="icon-"]{ color: #fff !important; }

.list td:first-child { z-index: 1; }

add to your custom.css in GUI: .sticky.bar.fixed .icon-code-fork:before { color: inherit !important; } #sub_nav a:hover, a:hover i[class^="icon-"], ....

Change: include/client/header.inc.php include/staff/header.inc.php  

} .list td { /* position: relative !important;*/  in staff_mobile.css changes the behaviour, but destroys the ticket view.
