Hi, is there any update on this issue?
Let me know any plugins I can use for FB Like!

Thanks.

I used a plugin “WP Social Bookmarking Light” and customized CSS a little bit because it didn’t show properly in default.

On its settings page, styles tab, I added the following codes:
.wp_social_bookmarking_light{
position: absolute;
z-index: 9999 !important;
}
.wsbl_facebook_like iframe{
z-index: 9999;
overflow: visible;
}
#main > .fullsize { z-index: 9999999999 !important; }

(only your code added at the last line worked so far)

Is there anyway to put main content text behind with z-index settings?
