Redirect 301 stops working after migration

I had our site working under a development subdomain, but when we moved it something must have changed, because the .htaccess file in the public_html folder no longer processes “Redirect 301” lines.

Every time I use the url to be redirected into the request, it goes to the root “/” and renders the index.php page. This is with caching turned off. I get no errors. If I put the url I want it redirected to into the request, the page I want to see is displayed correctly.

I’ve tried this with static pages as well. The problem does not seem to be anything having to do with the file system. Are there plugin conflicts that might be happening? Is there something failed to be set up in cPanel?
