WordPress site not redirecting to dashboard after login

Seems like some others developed the site. If you are coder/programmer try the below

1. Login to hosting
2. Open PHP My Admin or any mysql UI tool
3. Open Prefix_users, usually this will be wp_users
4. see list of users and check if you have admin permissions. Sample below
   user_id – specific user id
   meta_key – wp_capabilities
   meta_value – a:1:{s:13:”administrator”;s:1:”1″;}

then save the DB record. Else get programmer support
