Patch for fixing notices and warnings

polylang-1.6.5

I got some errors when using with my plugin Polylang – Translate URL Rewrite Slugs but I’m sure it could help for others circumstances.

I had an additional “isset” to the function parse_query of the file frontend/frontend.php.

The patch

diff --git a/frontend/frontend.php b/frontend/frontend.php
index 61bd775..84c5bd3 100644
--- a/frontend/frontend.php
+++ b/frontend/frontend.php
@@ -103,7 +103,9 @@ class PLL_Frontend extends PLL_Base {
 				$query->set('post_type', 'post');

 			// do we query another custom taxonomy?
-			$taxonomies = array_diff(wp_list_pluck($query->tax_query->queries, 'taxonomy'), array('language', 'category', 'post_tag'));
+			$taxonomies = array();

 			// unset the is_archive flag for language pages to prevent loading the archive template
 			// keep archive flag for comment feed otherwise the language filter does not work

Thanks!
