I'm getting the error below...
Warning: implode() [function.implode]: Invalid arguments passed in \wp-content/themes/mytheme/functions.php on line 1335
at...
function my_get_tags_sitemap(){
if ( !function_exists('wp_tag_cloud') || get_option('cb2_noposttags')) return;
$unlinkTags = get_option('cb2_unlinkTags');
echo '<div class="tags"><h2>Tags</h2>';
if($unlinkTags)
{
$tags = get_tags();
foreach ($tags as $tag){
$ret[]= $tag->name;
}
//ERROR OCCURS HERE
echo implode(', ', $ret);
}
else
{
wp_tag_cloud('separator=, &smallest=11&largest=11');
}
echo '</div>';
}
Any ideas how to intercept the error. The site has exactly one tag.

It happens when $ret
hasn't been defined. The solution is simple. Right above $tags = get_tags();
, add the following line:
$ret = array();
You can try
echo implode(', ', (array)$ret);
function my_get_tags_sitemap(){
if ( !function_exists('wp_tag_cloud') || get_option('cb2_noposttags')) return;
$unlinkTags = get_option('cb2_unlinkTags');
echo '<div class="tags"><h2>Tags</h2>';
$ret = []; // here you need to add array which you call inside implode function
if($unlinkTags)
{
$tags = get_tags();
foreach ($tags as $tag){
$ret[]= $tag->name;
}
//ERROR OCCURS HERE
echo implode(', ', $ret);
}
else
{
wp_tag_cloud('separator=, &smallest=11&largest=11');
}
echo '</div>';
}
