Installation Issue – The file ‘wp-config.php’ already exists.

Try recreating the wp-config.php file:
– First, save your existing wp-config.php file as wp-config.phpOLD.
– To recreate a new one, make a copy of wp-config-sample.php (which comes with the WprdPress) and add all of your database connection details.
– Then save the new file as wp-config.php and upload it to your WP folder.

I am currently also having this issue – but the answer above didn’t seem to work for me?

How I fixed this issue: I had tried an older version of WP no help, but I was deleting my database and renaming it the same thing and that could have been an issue. so I created a database with a different name but used the same user and credentials.

I use backupbuddy to import the theme and wp. it gives you the option to rename the file the database if built in. not sure if the WP version allows for this.

so instead of wp_ I changed it to cm_ and the config installation warning and url redirect left for good.

Had same issue, this answer from SO helped:

The file ‘wp-config.php’ already exists. If you need to reset any of the configuration items in this file, please delete it first.

I’m having the exact same problem. It’s a clean & fresh install & DB.

It was indeed the browser cache. @nikodemsky is correct.

Had the same issue after migrating a site. It was the browser cache.
