The advanced translator only shows the title of the page with an error in the debug log.
WordPress database error Unknown column 'wrap_tag' in 'field list' for query
SELECT id, name, value, wrap_tag, type, title
FROM wp_icl_strings
WHERE string_package_id=18
ORDER BY location, id ASC made by shutdown_action_hook, do_action('shutdown')
Solution:
1- Take a database backup
2- Run the following query
ALTER TABLE wp_icl_strings
ADD `location` BIGINT unsigned NULL AFTER `string_package_id`,
ADD `wrap_tag` VARCHAR( 16 ) NOT NULL AFTER `location`;
3- Update the page in the default language
4- Update the Translation
