MainWP Cache Control extension allows you to automatically purge the Cache on your child sites after performing an update of WP Core, Theme, or a Plugin through the MainWP Dashboard. Currently supported caching solutions are

• Cloudflare

and the following caching plugins:

• Breeze
• LiteSpeed Cache
• Siteground Optimizer
• Swift Performance Lite and Pro
• WP Fastest Cache
• W3 Total Cache
• WP Rocket
• Hummingbird Performance
• Cache Enabler
• Nitropack
• Autoptimize
• Nginx Helper

Overview of when the last automatic Cache purge occurred and what the currently detected Caching solution is for your Child sites can be found in the table located on MainWP > Sites > Manage Sites page.

Manually clear cache

The cache will be cleared automatically upon WP Core, Theme, or a Plugin update, but you can also manually trigger the clear.

From the Manage Sites table

Cache can be cleared for any number of sites from the Manage Sites page.

Select a number of desired sites, or all of them, and then from the Bulk Actions menu, select Clear Cache Control, and then click Apply.

Using widgets

Cache Control widgets are located on the Overview page and the Individual Child Sites Overview pages.

Locate them and simply click the Clear Cache button. If you do not see the widget, you may need to enable it from the Page Settings.

Cloudflare cache purging

For the Cloudflare cache purging to work, you must enter a valid Cloudflare API Email and Cloudflare API Key and enable “Use Cloudflare Cache API” setting.

NOTE Since version 4.0.1, the Cache Control extension will handle cache purging of both Cloudflare and the supported caching plugin at the same time.

Previously, if both caching solutions were present, only the caching plugin was supported.
