Error when migrating ojs from localhost to server

i had upgrated ojs in my localhost now when i migrate that code in server error comes when i click in register button

Please provide more detail.

  • OJS version
  • extract of your PHP error log
  • did you modify for your server correctly?
  • did you configure .htaccess rules?
  • did you run the upgrade.php script for your server, too?
  • why did you tag this post Open Monograph Press when you are using OJS?
