Custom subdomain with Heroku for WordPress blog shows herokuapp.com URL on clicking the post

I have a Rails app for root domain www.xyz.com which is hosted on Heroku. It works perfectly: all the URLs and products are shown with the proper custom domain.

I have created blog using WordPress which is a separate Heroku app and hosted on the subdomain blog.xyz.com. The landing page works fine. However when I click on any post the URL changes to *.herokuapp.com.

I have added a CNAME record in GoDaddy for the blog subdomain and added custom domain with following command:

heroku domains:add --app heroku-blog-wordpress-app-name blog.xyz.com

How do I get WordPress to use the correct domain?

Solution

  • This has nothing to do with DNS. WordPress just doesn't know what domain it should use when it generates URLs.

    1. Log into WordPress
    2. Navigate to Settings → General
    3. Update the WordPress Address (URL) and Site Address (URL) values to use your blog.xyz.com domain
    4. Save your settings

    WordPress should now build URLs using the correct domain.
