I have not manually changed it. I exactly forget by which plugin i have changed it for security purpose. And yes, it was ok till yesterday. But, still now, when i enter to “EDIT PROFILE” option, the same username instead of “admin” is shown. So, i can’t figure out whats happening. When i look on phpmyadmin even, username_sitemeta shows, site_admins as a:1:{i:0;s:5:”myusername”;}
—- While in the process of replying, i have solved this issue. I have checked myusername_users in phpMyadmin, there i saw user_login has been changed from my username to admin, so i edited and changed back to the same old one, and magically it worked. Anyway thankx for the reply—-
