[otrs] Remove icon from Agent and Customer interface - Help

Hi, I'm trying to remove the "ticket email" icon from the agent interface and "Logout" icon from the customer interface. I found reading the previous emails, and I tried to modify the AgentNavigationBar.dtl, but this file has one block that is responsible for more than one icon and I just want to remove one of them. <snip> <!-- dtl:block:Item --> <td valign="top" align="center" class="nav">

<br>$Text{"$QData{"Name"}"}</a></div> </td> </snip> I tried to comment the lines bellow in the config.pm, without success: $Self->{'Frontend::Module'}->{'Logout'} = { Description => 'Logout', NavBar => [ { Description => 'Logout', Name => 'Logout', Image => 'exit.png ', Link => 'Action=Logout', NavBar => '', Block => 'ItemPre', Prio => 100, AccessKey => 'l', }, ], }; Does anybody could help me, please? Thanks a lot. Cristiane
