Background of the issue:
I've removed several languages from my site hidden link and added a 301 redirect for all their pages in the htaccess file. I also added 301 redirects for pages from languages that were maintained on the site to their new page name without a .html extension. The latter redirects work fine.
Symptoms:
The 301 redirects for the removed languages are not working properly.
Questions:
Why are the 301 redirects for the removed languages not working?
Is there a specific configuration needed in the htaccess file for removed languages?
Could a plugin help resolve the redirect issue for removed languages?
