Always Have To Delete Cache After Update Or Page Is Blank

Hi Guys, For about the last 6 months almost every time i have updated wp fastest cache none of my website load correctly and most of the websites are blank, i have to log into the back end of every website and click the delete cache option from your plugin settings, then the website works again.

Would you know why this happens or is there a time element, ie, if i update the plugin and my website is blank, if i wait a number of hours, will it work again without me having to log in and click delete cache.

I’ve only asking now as when i update the plugin, more and more customers now are saying their website is down, but when i log in and click delete cache, everything works again, thanks in advance guys… ??
