OK, that is weird. It’s possible your hosting service installed the plugin. No hosting service or other plugin developer has told me they are installing this plugin on peoples’ sites.
It’s not hard to imagine that a hosting service would want to install the plugin in customer sites. It reduces MariaDB / MySQL overhead, and so it saves power and makes things faster for their customers.
What hosting service do you use?
Hi, the owner asked the hosting support about it … and YES they installed the plugin. Bad practice imho without a notice.
I guess activating it does the job and then we can simply remove it or needs to stay active?
