You can’t have a dash as part of a variable’s name. Change $sample-image to $sample_image. Looks like you have to do that in three places.

Also, your one line of code would be better as:

<?php $sample_image = get_post_meta(the_ID(), 'sample-image', true); ?>

What you are doing above is actually one of the reasons why I originally wrote the Get Custom Field Values plugin. All this code of yours:

<?php $sample-image = get_post_meta($post->ID, 'sample-image', $single = true); ?>
			<div id="sample-image">

				<?php // if there's a thumbnail
				if($sample-image !== '') { ?>
					<p>
						<img src="<?php echo $sample-image; ?>" />
					</p>
				<?php } ?>
			</div>

would just be this with the plugin:

<div id='sample-image'>
   <?php echo c2c_get_custom('sample-image', '<p><img src="', '" /></p>'); ?>
   </div>

(You could put the div tags in the call to the function too so that the sample-image div also doesn’t display if there is no sample image. But the way your original is coded, the div will always display, so my c2c_get_custom example behaves that same way.)

WordPress will create custom feeds on-the-fly for you if you provide additional query arguments:

<a href="http://yoursite.com/feed/?cat=3,7,8,11">Feed 2</a>

<a href="http://yoursite.com/feed/?cat=1,2,3,7,10">Feed 3</a>

Obviously, modify the domain to match the root of your WP site (which, if running in a subdirectory, should also be included: i.e. http://your-real-domain.com/wordpress/feed/).

By default the plugin outputs each listed post within <li></li> tags. So you need something like:

Recent Posts
<ul>
<?php c2c_get_recent_posts(3); ?>
</ul>

Or define your own format via the function’s second argument (read the docs for this on the abovementioned page).

Ok, do these also:

1. Remove this line:
echo "<li>";

2. Change this line (near the very end of file):

echo "$link</li>n";

to this:

echo "<li>$link</li>n";

I had written a plugin (heretofore unreleased) that allows you to do the above. I make no guarentees about it, but last I remember it worked. You can download the zip of it here. You can see the code for it here.

Just unzip the .zip in your wp-content/plugins/ directory. Then edit it to identify (a) the custom fields you want to add to the “Manage Posts” page, and (b) the existing columns you want removed. Sorry, no admin screen for it at the moment.

For example, using what you said, to add custom field to post listing, edit this variable like so:
$custom_fields_to_show_in_listing = array(
'country_name' => 'Country',
);

To remove existing columns (such as the author and category columns), change this relevent section:
$listing_columns_to_remove = array('author', 'categories');

Remember, you’re editing the plugin file to add/change the above code, not your templates or WP core files.

Then, of course, activate the plugin.

If you try it, let me know how (if) it works.

get_currentuserinfo() is a replacable function, hence its inclusion in the pluggable-functions.php file. As such, the function needs to load AFTER all the plugins have been loaded (unlike in pre-1.5.1 versions where it got loaded BEFORE plugins).

What this means for plugins is that you can’t call on get_currentuserinfo() in global space. I haven’t taken a look at the code for Exhibit, but that is my guess as to what it’s doing and why it’s now a problem.

It’s very likely other plugins will be likewise affected.

Would your server also be a Windows server?

Don’t reinstall WP on account of the plugin. Permissions might be set incorrectly for the plugin’s file(s) and/or directory. Do you have shell access to your plugin’s directory? If so, can you check owner and file permissions? What operating system is your server and what web server are they using?
