Version 1.6.33.2 crashes my web site

Hi there,
I had Version 1.6.33 running fine.
This morning I saw an update available so I decided to upgrade from the plugin page (no manual download). Big mistake ! It crashed the full web site.
FOr now I will keep the 1.6.33 version.

I enabled DEBUG mode to see the error.
I see a polylang.php. FYI, I am running last version of WPML on the site.

Fatal error: Uncaught TypeError: Argument 3 passed to WordPress\Plugin\Encyclopedia\Polylang::filterGettextWithContext() must be of the type string, null given, called in /sites/corliweb/www/web_main/wp-includes/class-wp-hook.php on line 287 and defined in /sites/corliweb/www/web_main/wp-content/plugins/encyclopedia-pro/classes/polylang.php:21 Stack trace: #0 /sites/corliweb/www/web_main/wp-includes/class-wp-hook.php(287): WordPress\Plugin\Encyclopedia\Polylang::filterGettextWithContext() #1 /sites/corliweb/www/web_main/wp-includes/plugin.php(212): WP_Hook->apply_filters() #2 /sites/corliweb/www/web_main/wp-includes/l10n.php(257): apply_filters() #3 /sites/corliweb/www/web_main/wp-includes/l10n.php(392): translate_with_gettext_context() #4 /sites/corliweb/www/web_main/wp-content/plugins/wpml-string-translation/classes/MO/JustInTime/MO.php(49): _x() #5 /sites/corliweb/www/web_main/wp-includes/l10n.php(178): WPML\ST\MO\JustInTime\MO->translate() #6 /sites/corliweb/www/web_main/wp-includes/l10n.php(289): translate() #7 /sites/corliweb/www/web_main/wp-content/plugins/lana-downloads-manager/includes/class-lana-download-widget.php(14): __() #8 /sites/corliweb/www/web_main/wp-includes/class-wp-widget-factory.php(61): Lana_Download_Widget->__construct() #9 /sites/corliweb/www/web_main/wp-includes/widgets.php(115): WP_Widget_Factory->register() #10 /sites/corliweb/www/web_main/wp-content/plugins/lana-downloads-manager/lana-downloads-manager.php(49): register_widget() #11 /sites/corliweb/www/web_main/wp-includes/class-wp-hook.php(287): {closure}() #12 /sites/corliweb/www/web_main/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters() #13 /sites/corliweb/www/web_main/wp-includes/plugin.php(484): WP_Hook->do_action() #14 /sites/corliweb/www/web_main/wp-includes/widgets.php(1795): do_action() #15 /sites/corliweb/www/web_main/wp-includes/class-wp-hook.php(287): wp_widgets_init() #16 /sites/corliweb/www/web_main/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters() #17 /sites/corliweb/www/web_main/wp-includes/plugin.php(484): WP_Hook->do_action() #18 /sites/corliweb/www/web_main/wp-settings.php(557): do_action() #19 /sites/corliweb/www/web_main/wp-config.php(99): require_once(‘/sites/corliweb…’) #20 /sites/corliweb/www/web_main/wp-load.php(37): require_once(‘/sites/corliweb…’) #21 /sites/corliweb/www/web_main/wp-blog-header.php(13): require_once(‘/sites/corliweb…’) #22 /sites/corliweb/www/web_main/index.php(17): require(‘/sites/corliweb…’) #23 {main} thrown in /sites/corliweb/www/web_main/wp-content/plugins/encyclopedia-pro/classes/polylang.php on line 21
