Hi everybody I have an error when updating or creating a new course on my opigno... Can't find the issue... I have just create 3 new fields for the course node to display on the course page and the certificate. Everything was working fine and suddenly, when I go to the course page again, I get a white page... I can still access the course that have not been updated... I have enabled maintenance mode and displaying error message on the platform and I got this : When I edit a course and go back to the course administration list --> Warning : array_keys() expects parameter 1 to be array, null given dans EntityReference_SelectionHandler_Views->validateReferencableEntities() (ligne 141 dans xx\xx\profiles\opigno_lms\modules\contrib\entityreference\plugins\selection\EntityReference_SelectionHandler_Views.class.php). Warning : array_flip() expects parameter 1 to be array, null given dans entityreference_field_validate() (ligne 223 dans xx\xx\profiles\opigno_lms\modules\contrib\entityreference\entityreference.module). Warning : array_diff_key(): Argument #2 is not an array dans entityreference_field_validate() (ligne 223 dans xx\xx\profiles\opigno_lms\modules\contrib\entityreference\entityreference.module). Notice : Undefined index: drupal dans update_requirements() (ligne 35 dans xx\xx\modules\update\update.install). On the white page of the updated course --> Additional uncaught exception thrown while handling exception. Original PDOException: in locale() (line 749 of xx\xx\modules\locale\locale.module). Additional PDOException: in dblog_watchdog() (line 160 of xx\xx\modules\dblog\dblog.module). Hope you could help me ! Many Thanks

White page when updating or creating a new course

Hello, I have changed the content of the different fields in the course parameters and everything is OK now... very strange The errors mentionned above are still there, but are not related to the white page problem...
