[Plugin: Solr for WordPress] Two errors when performing search

I’m using the Suffusion theme, not sure if that matters.

I tried activating SOLR but I receive two errors when I perform a search (see below).
http://wordpress.org/extend/plugins/solr-for-wordpress/

Error 1:
Warning: Invalid argument supplied for foreach() in /hermes/web02/b1930/moo.caringfamiliescom/blog/wp-content/plugins/solr-for-wordpress/template/s4w_search.php on line 67
Line 67:
foreach($results[‘results’] as $result) {

Error 2:
Warning: Invalid argument supplied for foreach() in /hermes/web02/b1930/moo.caringfamiliescom/blog/wp-content/plugins/solr-for-wordpress/solr-for-wordpress.php on line 890
Line 890:
foreach ( $facet_on_custom_fields as $field_name ) {

So I’m not quite sure what to make of this.
