Hey Mario, let's walk through how to strip Gulp out of your WordPress theme step by step—since you don't have access to the Gulp environment and are working via FTP/WordPress admin, this will be focused on manual, no-command-line steps that you can do directly in your theme files:

Step 1: Figure out which CSS/JS files WordPress actually uses #

First, you need to stop guessing which of those 3 identical files is the one live on your site. Here's how:

• Open your theme's functions.php file (via WP admin > Appearance > Theme File Editor, or FTP).
• Look for lines starting with wp_enqueue_style (for CSS) or wp_enqueue_script (for JS). These lines tell WordPress which files to load. For example:

  wp_enqueue_style( 'main-theme-style', get_stylesheet_directory_uri() . '/css/style.css', array(), '20240520' );
  

• The path in that line (like /css/style.css) is the only file you need to edit going forward. The other two identical files are either:
  • Uncompiled source files (usually in a src folder, like src/scss/style.css)
  • Old compiled output from Gulp (maybe in a dist folder, like dist/css/style.css)

Step 2: Delete Gulp's configuration files #

Next, remove all the files that power Gulp—you won't need them anymore:

• Delete gulpfile.js (or gulpfile.babel.js if it exists) — this is Gulp's main setup file.
• Delete package.json and package-lock.json (or yarn.lock if you see it) — these list Gulp's dependencies, which you don't have installed anyway.
• If there's a .gitignore file, you can leave it, but you can remove any lines referencing Gulp output folders (like dist/ or css/) if you want—though this isn't strictly necessary.

Step 3: Clean up redundant folders #

Now get rid of the duplicate files/folders that are just cluttering things up:

• Delete the src folder (if it exists) — this is where the original, uncompiled code lived, and you won't be using Gulp to compile it anymore.
• Delete any dist folder (if it exists) — this was Gulp's output directory, and WordPress isn't loading files from here (you confirmed that in Step 1).
• Double-check that you only keep the CSS/JS folder WordPress is using (like the /css/ folder from the example above) — delete any other folders with identical files.

Step 4: Adjust your workflow for future edits #

From now on, you only need to edit the CSS/JS files that WordPress is actually loading (the ones you found in functions.php). No more editing 3 files at a time!

• If the original code was written in SCSS (a CSS preprocessor), don't worry—you can edit the compiled CSS file directly. It's just plain CSS now, so you can add/modify styles without needing Gulp.
• After making edits, clear your WordPress cache (if you use a caching plugin) and your browser cache to make sure changes show up.

Critical Precaution Before You Start #

Backup your entire theme folder first! Download a copy to your local computer via FTP before deleting any files. That way, if you accidentally remove something important, you can restore it quickly.
