If you are using a plugin that includes custom post types you may run into the following PHP error:

[12-Nov-2011 19:27:32] PHP Catchable fatal error: Object of class WP_Error could not be converted to string in …/wp-content/themes/techozoic-fluid/functions.php on line 669

The problem is that the function tech_breadcrumbs() assumes that categories always exist for a post, so you end up with an error. To fix this, change this:

} elseif ( is_single() && !is_attachment() ) {
$cat = get_the_category();
$cat = $cat[0];
echo get_category_parents($cat, TRUE, ‘ ‘ . $delimiter . ‘ ‘);
echo $currentBefore;

to this:

} elseif ( is_single() && !is_attachment() ) {
$cat = get_the_category();
if ( $cat )
{
$cat = $cat[0];
echo get_category_parents($cat, TRUE, ‘ ‘ . $delimiter . ‘ ‘);
}
echo $currentBefore;

There are other problems with custom post type – the text “Filed in” still shows up for example, but this fix will at least let the page load…

Thanks I’ve incorporated this fix in the upcoming version.
