No entries in htaccess

Hi there,

i installed your plugin because the redirect solution is nice. The regeneration of the images worked without any problems. The folder uploads-webpc was created and there are a lot of images in it.

When I check the type in the DevTools still jpeg is delivered.
The .htaccess is still untouched. There is no WebP Section injected.
Even when i copy the lines manually into the htaccess i dont have success.

mod_mime, mod_rewrite and mod_expires should be enabled.
