WordPress enforces CamelCase
As of WordPress 3.0, you cannot type WordPress incorrectly in your titles or content. A patch was introduced to filter out any bad formatting of the WordPress name and replace it with the proper CamelCase format. Notice the following screenshot of my content area which includes several mis-formattings of WordPress that are formatted automatically.
So, patch author, Matt Mullenweg, wants to set the record straight that WordPress is spelled with a capital P. I guess the motivation of this is for brand integrity, however, this has caused quite a ruckus among the orthodox GPL folks. We won’t go into that on this post. If you wish to continue misspelling WordPress, you can add this to your functions file.
remove_filter('the_content', 'capital_P_dangit', 12); remove_filter('the_title', 'capital_P_dangit', 12); remove_filter('comment_text', 'capital_P_dangit', 12);
