My .htaccess file doesn't work properly.

A typical FeedPress redirection in a .htaccess (on an Apache web server) file looks like that:

# BEGIN FEEDPRESS RewriteEngine On RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC] RewriteCond %{HTTP_USER_AGENT} !FeedPress [NC] RewriteRule ^feed/?$ [R=302,NC,L] # END FEEDPRESS 

It's a 6-line block that shouldn't be separated.

You should put it at the very beginning of your .htaccess. Please note that if you have multiple feeds to redirect, you should create separate blocks for each feed.

Finally, the last line must be customized according to the original feed address and the FeedPress feed address. You can test the last RewriteRule line with this online tool.
