We're using Drupal 7.14.
We get "Warning: htmlspecialchars() expects parameter 1 to be string, array given in check_plain() (line 1572 of /usr/local/www/.../.../includes/bootstrap.inc)." when we access the "Views" pages that has "exposed filters" in the filter criteria. I think this warning fires when there're multiple exposed filters...
We cannot upgrade Drupal version yet as a solution.
Views version is 7.x-3.7
