 * Hello,
 * So the plugin is breaking the “preview” of posts when previewing them from the
   text editor.
 * I tried deactivating plugins and reactivating them and found out that the WP 
   Last Modified is causing it.
 * The problem only shows when previewing unpublished/new drafts posts.

 * Can you make sure the plugin doesn’t output itself during previews?
