Preview DNS and WordPress Content
Be careful when using WordPress® with Preview DNS enabled on your site.
WordPress uses full URLs to link to your images and posts. If you use Preview DNS to create content, then your site uses the Preview DNS domain name for your URLs.
This is bad for two reasons. First, search engines index the wrong links. Second, when your Preview DNS expires, your links break.
Once you’re ready to turn off Preview DNS, you can use the Search and Replace plugin to find all instances of mycooldomain.com.preview.com and replace them with mycooldomain.com. For more information, click here.
