In this blog post we show you some tips and tricks on how to enhance your WordPress installation by optimizing wp-config with features and how to make the entire installation safer.
The wp-config.php is the most important file of a WordPress installation. It contains the access data to the database. It also has other features for running WordPress, such as controlling the PHP memory limit on your server, the maximum number of post-revisions, and so on. It’s your most important file, and it needs to be protected from external intrusion.
Another important note before you make changes to the wp-config.php: make a backup of the current wp-config.php, so you can restore it when something goes wrong.
Anything added to the file with new code should be preceded by the “For Developers” comment (* For developers: WordPress debugging mode.).
You also need an HTML editor and an FTP client so you can access your server.
