Hi Virginia,
Regarding that heading please open light2.css from your Afterburner css dir and find this code :.article_row {margin:0 -10px 15px;overflow:hidden;}
and try to change it to :.article_row {margin:0 -10px 15px;}
and see if that helpes
The button issue is caused by not plugin specified css from one of your plugins - it adds a margin to all buttons on the site!
To fix it please open wp.css from your css dir and find this code :form#commentform input {
margin-bottom:10px;
padding:2px 5px;
}
and change it to :form#commentform input {
margin-bottom:10px;
padding:2px 5px;
margin-top: 0 !important;
}
Tell me how it went
Jakub
