When to do a Full Cache Purge

After updating some settings in your NitroPack account, a full cache purge is required for the changes to take effect on your website.

In this article, we've outlined which settings changes require a full cache purge. These settings (like Custom CSS and Custom CDN Domain Name) have a YES next to their name under the Full Purge Required column. You can do a full cache purge by clicking the "Purge Cache" button in the Dashboard.


The Full Purge Recommended column is for the settings whose changes take effect even without a full purge. However, we still recommend doing a complete purge for settings with a YES status in this column. This ensures the same fix is applied on all pages.

  • How much CDN will full purges deplete?

  • Hi Jonathan,

    Purges do not relate to CDN usage. CDN usage is only incurred as your users visit optimized pages.

  • I have been having glitches on my website, no matter which setting I am at.

    I already put the setting all the way down to medium, which works better than on high.

    I purge the cache, everything works fine for a while and then returns and have to repeat.

    Even on medium it already defeats the purpose of getting nitropack, since the speed results are no better than without.
