[Plugin: Yet Another Related Posts Plugin] version 3.4 throws error: warning: array_merge(): argumen

Looks like the previous version didn’t overload this function, and this one just borked it. Here’s the offending function:

function get_option( $option = null ) {
		$options = get_option( 'yarpp' );
		// ensure defaults if not set:
		$options = array_merge( $this->default_options, $options );
		// some extra work is required for arrays:
		foreach ( $this->default_options as $key => $default ) {
			if ( !is_array($default) )
				continue;
			$options[$key] = array_merge( $this->default_options[$key], $options[$key] );
		}
		if ( !isset($options['weight']['tax']) )
			$options['weight']['tax'] = $this->default_options['weight']['tax'];

		if ( is_null( $option ) )
			return $options;

		$optionpath = array();
		$parsed_option = array();
		wp_parse_str($option, $parsed_option);
		$optionpath = $this->array_flatten($parsed_option);

		$current = $options;
		foreach ( $optionpath as $optionpart ) {
			if ( !is_array($current) || !isset($current[$optionpart]) )
				return null;
			$current = $current[$optionpart];
		}
		return $current;
	}

That zip did the trick for me. Thanks.
