I update mod from 1.5.1 to 15.3 but now the Private message menù doesn't open...
I replace all old file and i run /install/index.php, then i insert in adm/style/overall_header.html this code
<!-- IF S_IN_ACP_PRIVMSGS_MOD -->
<link href="style/acp_privmsgs_mod.css" rel="stylesheet" type="text/css" media="screen" />
<script type="text/javascript" src="style/acp_privmsgs_mod.js"></script>
<!-- ENDIF -->
after <link href="style/admin.css" rel="stylesheet" type="text/css" media="screen" />
but the mod doesn't work
