On one of my client's site, I see that my plugin's JS and CSS files are minified.

Trying to identify what causes the files to minify, I tried to deactivate all plugins (except mine), and changing the theme to TwentyEleven. However, the files were still minified.

What else could cause the files to be minified?

  • Where do the minified files reside? Has there been a plugin such as W3TC active?

  • @vancoder: The minified files are in wp-content/plugins/my-plugin/.../my-jsfile.js. I'm not sure whether the W3TC plugin was active in the past. I can't see it in the list of the plugins. Mar 8 '13 at 22:52
  • are u using mu-plugin folder? Mar 8 '13 at 22:53
  • of course, this is my plugin's folder. Mar 8 '13 at 22:58
  • Hmm, possibly it's being automatically minified server-side. Check the host's control panel? I assume there isn't a CDN involved? If there is, check the settings there too.

Did you check your hosting environment to see if they've enabled something like mod_pagespeed?
