Wordfence may warn sometimes.
In this case you shouldn’t worry about it because we always improve our plugin and we always update the source code of WP Fastest Cache but we don’t release new version always.
You can check the changes via wordpress logs page.

WP Fastest Cache Premium updates the plugin automatically but sometimes you can get problem about update.
We solved our problem with paypal. You can now purchase a premium license with Paypal. https://www.wpfastestcache.com/#buy
If you have already paid, you should have gotten an email from us which contains the zipped file.
Purchase your first license and see why 1,500,000+ websites globally around the world trust us.
