Stephen,
There's 2 issues at play. One is a minor conflict with your RocketTheme template. We already have a fix for that conflict with our Like button, but looks like we need to add it for our send button as well. Please update the /components/com_jfbconnect/assets/jfbconnect.css file. In there, you'll see:
.jfbclike iframe {
max-width: none !important;
}Update that too:
.jfbclike iframe, .jfbcsend iframe {
max-width: none !important;
}That will fix the width of the box.
To fix the height, you'll need to modify the following styles in your template to remove the overflow:hidden parameter. I can't tell you where the styles are due to the compression of your CSS files, but this should help:
#rt-content-top, #rt-content-bottom {
overflow: hidden;
}and
[id*="rt-sidebar"] .rt-block .module-surround, #rt-content-top .rt-block .module-surround, #rt-mainbottom .rt-block .module-surround, #rt-content-bottom .rt-block .module-surround { ... }Remove the overflow:hidden from both and test to make sure that doesn't cause other unforeseen issues.
Keep us posted on how it goes, and best of luck,
Alex
