# foreach() error in sidebar.php

 * Running wp 1.5, a modified Connections (renamed to Gone_Fishing) theme, and I
   recently added Weather Report plugin.
 * Periodically, I get the following error:
    Warning: Invalid argument supplied 
   for foreach() in /var/www/html/wordpress/wp-content/themes/gone_fishing/sidebar.
   php on line 4
 * `
    
   <?php
    $link_cats = $wpdb->get_results("SELECT cat_id, cat_name FROM $wpdb-
   >linkcategories WHERE (cat_id <> 19) ORDER BY cat_id desc"); foreach ($link_cats
   as $link_cat) { ?> <h2 id="linkcat-<?php echo $link_cat->cat_id; ?>"> <?php echo
   $link_cat->cat_name; ?></h2> <ul> <?php wp_get_links($link_cat->cat_id); ?> </
   ul> </li> <?php } ?>
 * Click Reload in Firefox, and the sidebar displays fine.

    Would
   really like to see the error go away permanently. Seems that when the error is
   returned, that there seems to be a longer than usual wait for anything to render
   in the browser.
