Same problem. Doesn’t seem to be enabling gzip compression. https://www.nadalinfotografia.com.br/
At the first time i installed, there was a weird problem, all the pages of wp-admin redirected to 404 and the site worked with some problems. I tested in google and the compression worked! I uninstalled the plugin because i cant access my admin. And then i installed the plugin again. The instalation worked perfectly, but the compression doesn’t. I tried many times, in different ways, but unsuccessful.
