The log reports the same error on the time!Anybody helps me?

The first error:
Invalid argument supplied for foreach() at /home/wwwroot/nextcloud/lib/private/L10N/Factory.php#200

The second error:
scandir() has been disabled for security reasons at /home/wwwroot/nextcloud/lib/private/L10N/Factory.php#198

The above two errors just be reported by the log again and again with no interrupt!

This means that scandir is blacklisted in the disable_functions settings in your php.ini. We need this method to fetch available languages from the available files.

See https://secure.php.net/manual/en/ini.core.php#ini.disable-functions for the PHP documentation for this method. Please adjust it to allow scandir to be executed.
