After trying to install one of the classified script, i tried to login to admin area with default login details.

But it showing ‘Invalid username/password. Login failed’

So I went into cPanel and opened phpmyadmin to reset the password and now apparently mysql won’t allow me to edit the tables.

This table does not contain a unique column. Grid edit, checkbox, Edit, Copy and Delete features are not available.

I fixed the issue using the below method.

Go to phpmyadmin -> password table – > Structure => click Unique (dropdown menu) and click Index.
