How to Replace WordPress Theme and Plugin Editor

The editors for WordPress theme and plugin are used to edit the active theme and plugin by modifying lines of coding stuff. That makes it possible for you to have a quick look at a certain theme or plugin to check if there is a need to make some changes. However, since the default editor is so plain that can no longer satisfy your needs, WordPress allows you to replace the default one to a customizable one.

In this way, certain rows, syntax and line numbers are highlighted and that makes it much easier to recognize the right parameters from the well-organized lines. Follow this guide with the method of replacing the default theme and plugin editor in a few steps. We are going to do so by means of a WordPress editor plugin.

Make Preparations for the Editor Replacement

In case that something goes wrong when modifying the theme and plugin editor, we suggest you to backup your website before everything. Granted that the editor cannot work normally due to the incorrect replacement, the backup makes allowance for unexpected needs. Having all things ready, you should set about installing the plugin on your website.

WP Editor Plugin

The selected plugin is WP Editor and that is used for an alternative of the default theme and plugin editor in WordPress. Besides, it can also replace the page and post editor. Once taking this plugin into effect, the theme and plugin editor would come with line numbers, line wrapping, active line highlighting, and some other features.

Log into your WP admin and search for WP Editor plugin to get a result as below. Click “Install Now” before activation and enable this plugin on your website. A new item “WP Editor” on your sidebar appears if you have successfully installed this plugin.

And then, set font size in pixels via Font Size mode and the default font size is in 12 pixels.

Check “Yes” or “No” option to enable or disable line numbers, line wrapping, active line highlighting, file upload and creating themes for the theme editor.
