I can't show facebook like button and comments box on jomsocial events

Content plugins fire certain events that JFBConnect is looking for in order to add the buttons to the pages. These events are only triggered by Joomla content and K2 content. No other extensions use them, including JomSocial.

Instead of our content plugin, I'd recommend that you look into our JFBCSocialShare module to display on your event pages instead. Otherwise, you can modify the JomSocial template files to manually insert our Easy-Tags like {JFBCLike} {JFBCComments} wherever you want those to display.

I hope this helps get you further along.

Sure, the settings we use for the JFBCSocialShare module are the following:
Layout: Button Count
Orientation: Horizontal
Position: Float
Margin: 5px
Padding: 5px 0px 0px 5px
Background: #FFF
Float from Top: 3000
Float from Left: 3000

Note, we also set the width in Facebook Options to 85. Without doing this you may have lots of whitespace.

For a border, you should just be able to add the following CSS to your page
