[Risolto] Errore nell'accesso a "impostazioni"

Nell'accedere alla sezioni "Impostazioni" di WPML il sito genera un errore. Ho provato a disattivate tutti i plugin ma il problema rimane.

Questo l'errore segnalato dal debug di WP:
Fatal error: Uncaught TypeError: Unsupported operand types: string / int in /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/classes/ATE/API/class-wpml-tm-ams-api.php:732 Stack trace: #0 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/classes/ATE/API/class-wpml-tm-ams-api.php(763): WPML_TM_AMS_API->request() #1 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/classes/ATE/API/class-wpml-tm-ams-api.php(834): WPML_TM_AMS_API->signed_request() #2 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/classes/ATE/API/class-wpml-tm-ams-api.php(796): WPML_TM_AMS_API->getSignedResult() #3 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/API/ATE/Account.php(17): WPML_TM_AMS_API->getCredits() #4 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/API/ATE/Account.php(48): WPML\TM\API\ATE\Account::getCredits() #5 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/classes/menu/translation-method/TranslationMethodSettings.php(72): WPML\TM\API\ATE\Account::isAbleToTranslateAutomatically() #6 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/fp/core/Either.php(207): WPML\TM\Menu\TranslationMethod\TranslationMethodSettings::localize() #7 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/fp/core/Either.php(257): WPML\FP\Right->map() #8 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/fp/core/Promise.php(24): WPML\FP\Right->chain() #9 /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/wp/classes/Hooks.php(50): WPML\FP\Promise->resolve() #10 /data/vhosts/villagioiellinoto.it/httpdocs/wp-includes/class-wp-hook.php(308): WPML\LIB\WP\Hooks::WPML\LIB\WP\{closure}() #11 /data/vhosts/villagioiellinoto.it/httpdocs/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #12 /data/vhosts/villagioiellinoto.it/httpdocs/wp-includes/plugin.php(517): WP_Hook->do_action() #13 /data/vhosts/villagioiellinoto.it/httpdocs/wp-admin/admin-header.php(118): do_action() #14 /data/vhosts/villagioiellinoto.it/httpdocs/wp-admin/admin.php(239): require_once('...') #15 {main} thrown in /data/vhosts/villagioiellinoto.it/httpdocs/wp-content/plugins/sitepress-multilingual-cms/classes/ATE/API/class-wpml-tm-ams-api.php on line 732
