Hello mate,
I can’t login with account that you gave.
– Fix your logo size issue, please open this file: (/testtemp/templates/ja_teline_iv/css/template.css)
find and change this snippet code:
#ja-header .main { height: 115px; padding: 0; }
to
<blockquote>#ja-header .main { /*height: 115px;*/ padding: 0; }</blockquote>
– About menu style, I see that you have switched menu to spilit menu, please try to switch it to mega menu, or change this code snippet (in this file /testtemp/templates/ja_teline_iv/css/menu/split.css) to get it looks better:
<blockquote>#ja-splitmenu { padding: 0; }</blockquote>
to
#ja-splitmenu { padding: 0; border-bottom:5px solid #CCCCCC;}
