# My plugin = WSOD

 * (@nickmoyer)
 * [12 years, 6 months ago](https://wordpress.org/support/topic/my-plugin-wsod/)
 * I followed this [tutorial](http://wp.tutsplus.com/tutorials/plugins/a-guide-to-wordpress-custom-post-types-creation-display-and-meta-boxes/)
   I thought very closely but when I finished it, my plugin works but it gives every
   other page on the site the WSOD! Once I deactivate the plugin, my other pages
   work again. I am running this on my mac using MAMP if that helps at all. I wanted
   to get it all finished before I upload and test online even though my site isn’t
   live.
 * Below is my code. Any ideas on what the heck I did wrong? Thank you so much for
   any help you can give me.
