 * There are a couple things you can try to resolve this problem.
 * first you can [manually reset your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F).
   
   Second you can [manually reinstall the WordPress files](https://codex.wordpress.org/Updating_WordPress#Manual_Update).
 * Let us know how this works for you and if it doesn’t then please answer the question
   below with your reply.
 * Did you do an update to WordPress, your plugins, or change/update the theme you
   are using?
