PressPi (WordPress) Broken Layout

I know this is late, and you might have found the answer already, but I suspect you’ll need to do a serialized search and replace on the DB. You can’t just change the WP domain name in wp-config.php. The database still has entries for the setup domain name, whatever that might be (localhost?). You can use this tool: https://interconnectit.com/products/search-and-replace-for-wordpress-databases/

I use version 2, as it is just a .php file, but version 3 has a more useful interface. You’ll need the DB creds, the old url (“localhost”), and the new one (your IP, in this case.) After this, you’ll only be able to see a working, non-broken version, at the IP.
