I have installed magento 2.0.7 with CentoOS 7 / Apache 2.4.6 / PHP 7 / MariaDB 10. After applying the Japanese locale to "Interface Locale" under Account Setting (refer the link below), I get "HTTP ERROR 500" for accessing the admin console.
Found that the Japanese locale installation was incomplete. Consequently, I need a help for restoring the "en_US" locale by updating DB or Coding.
Please help me to resolve this issue by providing the steps to change the locale with using command line. Many thanks in advance.
