Are you using a plugin or something? I can see the code that is adding a border, but it’s not coming from the theme. It’s showing up in your source code which means its either a plugin or code you’ve added in manually somewhere.
Here is what is causing that border to show –
#igit_rpwt_thumb,
#description {
margin-left: 0px;
border: 1px solid #DDDDDD;
padding: 3px;
}
