Problem Description: When creating the menu translations I'm getting this error:
PHP Fatal error: Uncaught exception 'InvalidArgumentException' with message 'element_id and type do not match' in wp-content/plugins/sitepress-multilingual-cms/classes/core-abstract-classes/class-wpml-set-language.php:26
I can not access wp-admin anymore.
Solution: - Make a backup of your site (both files and database). - Update to the latest version WPML 3.3.6 or later. - Run the following SQL query:
DELETE
t
FROM `wp_icl_translations` i
JOIN `wp_icl_translations` t
ON i.element_id = t.element_id
AND SUBSTRING_INDEX(i.element_type, '_', 1) =
SUBSTRING_INDEX(t.element_type, '_', 1)
AND i.element_type != t.element_type
AND i.translation_id != t.translation_id
JOIN (SELECT
CONCAT('post_', p.post_type) AS element_type,
p.ID AS element_id
FROM wp_posts p
UNION ALL
SELECT
CONCAT('tax_', tt.taxonomy) AS element_type,
tt.term_taxonomy_id AS element_id
FROM wp_term_taxonomy tt) AS data
ON data.element_id = i.element_id
AND data.element_type = i.element_type
