WordPress MU

I have been trying to install WooTheme's Premium News Template - http://www.woothemes.com/2007/11/premiumnews/ - and there quick help says that it is compatible with WPMU however the thumbnails for posts, etc (thumbs.php) never appear correctly if at all. Anybody been able to install the theme before or have any suggestions?

If you bought it from them, the best place to go would be their forums for support. :)

It is one of their free themes unfortunately so there forums don't offer support on the topic. Thanks anyway.

The thumbnails are done with timthumb, and they know the fix.

You can double-check from this post:

Hi Andrea - you wouldn't by any chance happen to know how I can put that into effect in the thumb.php file included in the free download of Original News Theme would you? I tried - to the best of my knowledge using the article you recommended but I couldn't seem to get it to work. Thanks.

I have screaming kids in my ear today so you'll have to forgive me for not looking at this but please review the fix in this thread:

http://mu.wordpress.org/forums/topic/9305?replies=10

I don't know if it's different from the one you're looking at.

*sigh* Yes, little girl. You look very pretty in your pink dress but I'm trying to type.

You don;t put it in thumb.php.

You have to edit the code in the theme where it calls the timthumb script.

Ah well I wasn't quite sure it was the correct file. In this case what would I have to edit the below to to get the images to display in WPMU?

<?php if ( get_post_meta($post->ID, 'image', true) ) { ?> <!-- DISPLAYS THE IMAGE URL SPECIFIED IN THE CUSTOM FIELD -->

			<div class="featured-img" style="background:url(<?php echo bloginfo('template_url'); ?>/thumb.php?src=<?php echo get_post_meta($post->ID, "image", $single = true); ?>&h=200&w=350&zc=1&q=90) top left no-repeat;">
				<?php if ($counter == 1) { ?><div id="ribbon"><img src="<?php bloginfo('stylesheet_directory'); ?>/styles/<?php echo "$style_path"; ?>/ribbon.png" alt="Featured"  /></div><?php } ?> <!-- SHOW "FEATURED" RIBBON FOR FIRST POST ONLY -->
			</div>

The link I gave way up above explains how to do it. :)

Hi csladdin!

Did you manage to fix the problem?

I have the exact same problem and I would be very grateful if you would post the new version of the code.

Thanks in advance!
