Case Insensitive URL’s


This plugin runs automatically at the beginning of each page load to insure every request is handled in a case-insensitive manner.

This plugin forces all capital letters in a URL be changed to lowercase. For example: /MyPage becomes /mypage.

This plugin prevents 404 errors from case-sensitive URL’s. It also prevents costly mistakes if you’ve printed your marketing materials with a capital letter.


  1. Upload case-insensitive-urls to the /wp-content/plugins/ directory.

  2. Activate the plugin through the ‘Plugins’ menu in WordPress.


1) Does this plugin work with Multisite?

Yes! This has been fully developed to work with Multisite. If moving a Multisite, make sure to Network Activate the plugin.

2) How do I know if the plugin is working?

Simply type in any URL of a page on your site with capital letters, for example /Blog. Were you redirected from /Blog to /blog, if so, it’s working!
