hi i have the exact same problem and nothing worked for me either did you find a solution
Facebook removed border color from their api just add this to your css
.fb-like-box{
border:0px;
width:200px;
z-index:10;
height: 236px;
overflow: hidden;
position:relative;
top:-1px;
left:-2px;
}
.fb-like-box iframe{
left:-5px;
overflow:hidden;
position:relative;
top:-1px;
}
