Error With WP Debug Enabled (fix provided)

The plugin Seriously Simple Podcasting creates a custom post type Episodes. When WP Debug is enabled, the episodes show as 404 pages instead of displaying.

Turns out this is related to line 373 of class-custom_body_class.php:
$values = explode( ‘ ‘, $val );

Here’s the code that resolved this issue for me (replacing lines 371-383):

if ( ! empty( $res ) ) {

foreach ( $res as $k => $val ) {

// Only accept strings; ignore null/arrays/etc.

if ( ! is_string( $val ) ) {

continue;

}

$val = trim( $val );

if ( $val === '' ) {

continue;

}

// Split on any whitespace, skip empties.

$values = preg_split( '/\s+/', $val, -1, PREG_SPLIT_NO_EMPTY );

foreach ( $values as $value ) {

if ( ! in_array( $value, $rezult, true ) ) {

$rezult[] = $value;

}

}

}

}
