Steps to Keep Your WordPress Theme and Plugin Code Secure:

1st Step: Disable the Editor!

As you may know, every online project based on WordPress comes with a built-in editor. In case you are the one who prefers to edit their site’s code, you surely know what we are talking about. Moreover, WordPress dashboard allows you to change the code without having the access to cPanel.

It works thanks to the responsive WordPress templates that already contain a thoroughly written source. Given these points, we recommend you to disable the editor to keep your WordPress theme and plugin code secure. It is as easy as ABC. Just open your wp-config.php file and insert this code.

// Disallow file edit
define( ‘DISALLOW_FILE_EDIT’, true );

2nd Step: Disable PHP Error Reporting

So, PHP error reporting is the next thing you should disable to keep your WordPress theme and plugin code secure. To make a long story short, this feature is responsible for notifying you about the possible problems. Needless to say, you have seen these error messages a lot of times. It looks like a usable thing but, unfortunately, PHP error reporting can also be risky. To make things clear, such messages come with server path information. As a result, your online project will be hacked if malefactors get an error message.

Disabling PHP error reporting is easy as well. Firstly, go to your wp-config.php file. Secondly, copy these lines to it.

Don’t be afraid, it will not influence your customers. The valid inputs will work as usual.

Also, data validation is a pre-packed feature, so every WordPress website already has it. Still, sometimes users need to complete the customization process. As a result, you will construct the fully customizable input boxes to keep your WordPress theme and plugin code secure. How does data validation work?
