Invalid argument supplied for foreach() in Drupal\Core\Field\FormatterPluginManager

Hello,

I face off issues about PHP:

Warning : Invalid argument supplied for foreach() dans Drupal\Core\Field\FormatterPluginManager->getOptions() (/var/www/drupal-8/core/lib/Drupal/Core/Field/FormatterPluginManager.php ligne 176)
#0 /var/www/drupal-8/core/includes/bootstrap.inc(600): _drupal_error_handler_real(2, 'Invalid argumen...', '/var/www/drupal...', 176, Array)
#1 /var/www/drupal-8/core/lib/Drupal/Core/Field/FormatterPluginManager.php(176): _drupal_error_handler(2, 'Invalid argumen...', '/var/www/drupal...', 176, Array)

and Js:
Hook de thème token_tree non trouvé with Seven as admin theme

and this cause:
Filefield sources autocomplete doesn't work anymore
Megamenu doesn't show sub items depending on which page you are

I don't have enough element to know what I need to look for.

Thanks for help
