The wp-config.php file: One of the most loved WordPress feature for some, one of the worst nightmares for others.
There are countless tips and tricks in a plethora of articles, and you can’t get enough of them; however, this article is aiming to be different. In this article, we’re going to get familiar with eight new wp-config tricks that are less known than functionality such as turning off post revisions, increasing the memory limit, or other similar features.
Don’t forget to backup your installation! The tips in this article do not change any database values nor do they play with any files (except wp-config.php, of course) so you can just download a copy of your wp-config.php file, but you can backup your database and files to make sure.
Better safe than sorry—frequent backups are always good!
