Automatic constant page reloads

but wp fastest cache does not work on multisite.

ok, thanks, I didn’t know that.

you are welcome

I have WP Fastest Cache installed on a single instance, and it is constantly reloading the page after 1 or 2 seconds even after clearing the cache on the server and the browser.

Please take a look at the following tutorial.
