Wordpress Multisite 404 error

Question

I hope you can help.

I've setup a wordpress multiste and use WordPress MU Domain Mapping. I run 10 sites using this system with no problem. However, the latest site is generating a 404 error when I turn the domain mapping on.

example.com/domain works

domain.com is getting the 404 error.

I have:

• Disabled all plugins
• Enabled WP_DEBUG and nothing shows up
• Changed the www. and non www. versions to be primary
• Changed theme back to twentythirteen
• Disabled functions.php
• Increased PHP memory limit in wp-config and htaccess

None of the above fix the issue.

Any other ideas would be much appreciated

Thanks Mark

Does all domains registered at the same registar? You need to make sure you have right DNS settings.
