Back to the next task and the next task means editing the WP config dot php itself. So select it and click Edit. And we want to put these lines here right at the bottom. Now I've noticed that let's put them in. And what this does is disable editing in the dashboard. So you can't edit any files in the dashboard like you can with theme files sometimes.
And that means if anyone has access to your WordPress administration area that they can't edit the files, they can only says post two pages and stuff. It's bad enough, but it will stop further damage being done. I've noticed when you put this in that on my WP hyphen config files, some of them have this question mark tag closing PHP tag at the end, and some of them don't. So I'm just leaving that one in there. And we'll see changes and test the website and test the WordPress back end.
