I get this error: Undefined index: title Call to a member function slice() on null plugins\offline\sitesearch\components\SearchResults.php line 212 *

• @return ResultCollection */ protected function getPaginatorSlice($results) {

  return $results->slice(($this->pageNumber) * $this->resultsPerPage, $this->resultsPerPage);

  } }

Can you add this line here and see if this fixes things for you?

$modified = Event::fire('offline.sitesearch.results', $resultsCollection);
// Add this line right below
$modified = array_filter($modified);

yes thanks
