"The file 'wp-config.php' already exists

Hi,

I’m facing this issue “The file ‘wp-config.php’ already exists. If you need to reset any of the configuration items in this file, please delete it first. You may try installing now.” I can go to wp-admin, and I can go to frontend of any other page except homepage. When I’m on homepage, I get redirected to /wp-admin/setup-config.php and I get this message. I searched for the solution and I didn’t find it. I don’t have another website on that same root or some other directory within it.
