I delete the "WP Super Cache" and instoll "Nitro pack". They do the same thing

it's not related to rank math

This happened after I installing the RankMath plugin.

This error means that you already use or used other cache plugin. You need to write to author of plugin. 

Nitro pack is one of best cache systems

Hi

The plugin "WP Super Cache" gave me an error in atachet file. The file are quoting is empty. How can I fix this error.

There is a NitroPack plugin, what do you think about it, can we use it with the theme

It's the same plugin.

You can install any SEO plugin, Rank Math or Seo by yoast are recommended

Hi

I use you article "How to add statistic and tracking" and installing this plugin "Google Site Kit" but the Rehub – plugins section have old plugin "Rh Cloak Link" but it doesn't have "RH Link PRO"

Are need to install additional SEO plugin like "Yost".
