Caching is not working

I turned on Wordfence Falcon Engine with debuggind and then I checked FTP and saw – cached files incoming but when I visited website It wasn’t cached(as unlogged member). .htaccess it’s look OK. Website it’s not a subdomain.
Source of .htaccess:

#WFIPBLOCKS - Do not remove this line. Disable Web Caching in Wordfence to remove this data.
Order Deny,Allow
#Do not remove this line. Disable Web Caching in Wordfence to remove this data - WFIPBLOCKS
#WFCACHECODE - Do not remove this line. Disable Web Caching in Wordfence to remove this data.
