Okay, found the problem guys. It looks like the theme file somehow did not get included into the package. Also, there's a slight css fix necessary but this will be addressed in 1.2.5. To fix this, add the block of css codes into your template's css file,
body div#fd.es .jfbconnect-wrapper {
text-align: center;
}
body div#fd.es .jfbconnect-wrapper .social-login > div{
display: inline-block !important;
}
body div#fd.es .jfbconnect-wrapper .social-login .pull-left {
float: none !important;
margin: 0 !important;
}
body div#fd.es .jfbconnect-wrapper .social-login .pull-left a
{
display: inline-block !important;
}
body div#fd.es .jfbconnect-wrapper .social-login .pull-left a img{
max-width: 90px;
}
As for the missing theme file, download the attached file and upload it into /components/com_easysocial/themes/wireframe/facebook/
