Hej,
I get the same 404-error with the plugin and my speaking-permalink option, but i don’t use any caching plugin.
I use a standard apache-webspace. YOu can check my phpconfiguration at https://bolzplatzheld.de/phpinfo.php
here is my htaccess:
RedirectMatch 301 ^/([0-9]{4})/([0-9]{2})/(.*)$ https://bolzplatzheld.de/$3
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Thanks for your help
