Domain change: redirect works only on homepage

Hi!

I’m trying to move the domain “ca.academyofartbarcelona.com” to “academiadartbarcelona.cat”.

As you can see, the redirect works only in the homepage :-S According to the Codex, the things I’ve done until now are:

1. Change the WordPress and site URL in the General settings menu
2. Replaced all database entries from “ca.academyofartbarcelona.com” to “academiadartbarcelona.cat” with the plugin Search & Replace
3. Checked the .htaccess. WordPress has made this changes automatically and I think is all right:

   RewriteCond %{HTTP_HOST} ^ca\.academyofartbarcelona\.com$ [OR]
   RewriteCond %{HTTP_HOST} ^www\.ca\.academyofartbarcelona\.com$
   RewriteRule ^/?$ "http\:\/\/academiadartbarcelona\.cat\/" [R=301,L]

But, by checking the URLs outside the home at Google, you can see that there’s no redirection working. For example:

https://ca.academyofartbarcelona.com/professors/

It still works! And it should be redirected to https://academiadartbarcelona.cat/professors/

What’s happening? What I’m doing wrong? :-S
