My WordPress was running successfully until i reinstalled the WAMP server on my local machine.(due to some reason the WAMP got unistalled automatically and I had to reinstall it.) And the index.php file got overwritten with a new one.
Now I can access myphpadmin but when trying to access WordPress getting the installation screen. When I put the site title and email id to install it again, it says ‘Please provide a valid username’ and in the username field it says ‘User(s) already exists’
Please help me as I am new to WAMP and WordPress.
