Hello,
I use Wordfence on a few WP sites, with the normal cacheing on.
I wanted to activate the Falcon cache, but I got this alert:
"You are using an Nginx web server and using a FastCGI processor like PHP5-FPM. To use Falcon you will need to manually modify your nginx.conf configuration file and reload your Nginx server for the changes to take effect. You can find the rules you need to make these changes to nginx.conf on this page on wordfence.com. Once you have made these changes, compressed cached files will be served to your visitors directly from Nginx making your site extremely fast. When you have made the changes and reloaded your Nginx server, you can click the button below to enable Falcon."
I asked to my hoster and he said they have no Nginx or other proxies.
So what?
The website is on a linux shared server, WP 3.9.1 multisite (with subdirectories, not subdomains).
TIA
