Hello @codeby
Thank you for reaching out and I am happy to assist you with this.
In order to change the settings on subsites, the network admin must uncheck the “Use single network configuration file for all sites.” setting in Performance>General settings>Miscellaneous and save the settings.
After that, you need to go to the subsite dashboard, and in the Performance>General settings click on the button that says “Use specific settings”. Once that is completed navigate to the Performance>Page Cache.:



I hope this helps!
Thanks!
Thank you! Can I use relative link in sitemap?
i.e. /sitemap_index.xml (without domain name).
Hello @codeby
You are welcome.
You should use the complete link https://yourwebsite.com/sitemap_index.xml
Thanks!
Thank you.
Do I need enter a link here if I use Yoast addon on multisite?
Hello @codeby
Yes because preload is based on the sitemap you feed the plugin with. Based on that sitemap, the W3TC will preload the pages.
THanks!
Thank you!
But what does Yoast Extension for W3 Total Cache do? How it works?
