You can manually generate a wp-config.php file by locating the sample file named wp-config-sample.php (located in the root install-directory), editing it as required, and then saving it as wp-config.php.

The contents of the wp-config-sample.php file are in a very particular order. The order matters a lot. If you already have a wp-config.php file, rearranging the contents of the file may generate errors on your blog.

We can apply the wp-config file to enhance site security. In extension to adjustments to the file structure, we can secure down amazing features that could open undesirable vulnerabilities. First of all, we can incapacitate the file editor implemented in the admin panel.

How to start?

Firstly,the thing you require to do is to build a whole WordPress backup. The wp-config.php file is so important to a WordPress site that a small error will make your site inaccessible.

You will require an FTP client to link to your website. Windows users can install WinSCP or SmartFTP and Mac users can try Transmit or CyberDuck. An FTP client allows you to transport files between a server and your computer.

Link to your website using the FTP client. You will need FTP login information which you can get from your web host. If you don’t know your FTP login information, then you can ask your web host for support.

The wp-config.php file is usually located in the root folder of your website with other folders like /wp-content/.

What if you can't find the file?

Is the wp-config.php missing from your WordPress installation? It’s quite probable that you might not get a wp-config.php file at all. Just in case you don’t understand the wp-config.php file, just rename the “wp-config-sample.php” file to “wp-config” and that will follow the same purpose. You can do this right in the cPanel.

How to edit?

Firstly, go to the location where you find that file. Choose the file and click on download. Begin it in a text editor like Notepad. Here, you’ll be equipped to edit it. To edit the file, just make the modifications you need. This implies you can add your own code, edit the existing code, or even delete some of it. Save the modifications. Then, head back to the File Manager and upload it to the public_html folder. You can really overwrite the old file. Now that you know how to download, edit, and re-upload your wp-config file, you can try it yourself. This is severe stuff, here. Again, we can’t emphasise enough that accomplishing this without a backup and a platform site is downright dangerous. Do NOT do that in any situations. Always remember that backup is mandatory.
