Podaj szablon naglowek --> header_welcomeguest_register

header_welcomeguest_register ?? (Nie mam takiego)

header_welcomeblock_guest

                        <!-- Continuation of div(class="upper") as opened in the header template -->
                        <span class="welcome"> <a href="{$mybb->settings['bburl']}/member.php?action=login" onclick="$('#quick_login').modal({ fadeDuration: 250, keepelement: true }); return false;" class="login">{$lang->welcome_login} »</a> <a href="{$mybb->settings['bburl']}/member.php?action=register" class="register">{$lang->welcome_register}</a></span>

Sorry, pomyliłem się
Wklej to do global.css:

.register {
background: #7BA60D;
color: #FFFFFF;
display: inline-block;
padding: 5px 8px;
border: 1px solid #7BA60D;
box-shadow: 0px 1px 0px rgba(255, 255, 255, 0.2) inset, 0px 1px 4px rgba(0, 0, 0, 0.4);
font-size:11px;
}
.register a {
font-size:11px;
text-shadow: 0px 1px 2px rgba(0, 0, 0, 0.3);
}
.login a {
font-size:11px;
}

No prawie:

Usuń to z global.css:

#panel .upper a.register {
    background: url(../../../images/user_register.png) left  no-repeat;
    padding-left: 20px;
    margin-left: 10px;
    font-weight: bold;
}

@EDIT
I jeszcze to usuń:

#panel .upper a.login,
#panel .upper a.lost_password {
    background: url(../../../images/user_login.png) 0 no-repeat;
    padding-left: 20px;
    margin-left: 10px;
    font-weight: bold;
}
