I don't see sharethis buttons on regular posts either

I don't think I have any turned on right now, but they do work - just not on Intros...

Did you put the code in item footer? It may be disabled on Intro posts, just a thought.

Here's what I've got in my index.main.php:

<?php
			// Go Grab the featured post:
			if( $Item = & get_featured_Item() )
			{	// We have a featured/intro post to display:
				// ---------------------- ITEM BLOCK INCLUDED HERE ------------------------
				skin_include( '_item_block.inc.php', array(
						'feature_block' => true,
						'content_mode' => 'auto',		// 'auto' will auto select depending on $disp-detail
						'intro_mode'   => 'normal',	// Intro posts will be displayed in normal mode
						// - Ethan 'item_class'   => 'featured_post',
						'image_size'	 =>	'fit-400x320',
					) );
				// ----------------------------END ITEM BLOCK  ----------------------------
			
			
			if( $Item->ptyp_ID == 1500 ) $GLOBALS['MainList'] = NULL; 
						} 
			?>

Am I missing something here...or do I need to edit the sharethis.plugin.php?

I'm having the same problem here: http://wccoa.org/index.php/Nutrition/ - this is an Intro with ShareThis turned on.

Here's a post with it turned on: http://wccoa.org/index.php/BellinghamSeniorActivityCenter/

sam2kb just helped me finally fix this - the answer: Comment-out or delete line 128 in the plugin

THANKS SAM2KB!!!
