domains won't map

Starting a new thread as requested.

I can’t get the domain mapping plugin to work for my mulitsite network.

I followed all the instructions and the mapped domain ( ) just points to the main site ( ), which is then weirdly stripped of all css, instead of the intended subdirectory ( ).

Using most current version of WordPress with a subdirectory multisite install. Hosted on Dreamhost VPS. I tried rebooting the server, clearing browser cache, hopping up and down on one foot while waving my left hand, etc.

The domain mapping table is present in the database, but uses a different prefix (wp_jy5n57_domain_mapping), and the mapped domain is listed in the table.
