PHP warnings

I monitor the PHP warnings of my site with Rollbar because they are often a sign of larger issues.

Your plugin generates hundreds, if not thousands of PHP warnings monthly, of which the following is the most prevalent:

E_WARNING: unlink(/var/www/ultimatehackingkeyboard.com/wordpress/wp-content/cache/wpfc-mobile-cache/wordpress/index.html): No such file or directory

Would you fix this warning? These warnings are alarming, and they count toward my monthly Rollbar quota, increasing my expenses.

Thanks for your plugin! I’ll probably buy the pro version soon.
