You uninstall it like any other plugin: https://www.wpbeginner.com/beginners-guide/how-to-properly-uninstall-a-wordpress-plugin/
If your theme depends on it, then removing it will affect your theme. Theme issues should be directed to the theme author. We do not support themes.
Good luck.
@kprovance it´s already deleted in “plugins” but it shows on “tools”. How can i uninstall it completely from my site?
That’s usually an indication that a theme or plugin has embedded Redux in their product. Not only do I not know which plugin or theme is doing this, we have no control over how developers use Redux. You’d need to figure out which plugin has Redux embedded and then contact the developer of that product.
One way to tell which plugin it is, ironically, is to use that menu item and read the screen that opens. It will say which product is using Redux.
@kprovance i dont get it. I downloaded and installed redux from their official website and now i cant delete it from my site?
I just explained what the likely situation is. I can’t look through your WordPress installation for you. You have to do that. Also, one cannot download Redux from our website. Once you determine which plugin ort theme is running an embedded version of Redux, you can take it up with them, as again, we have no control over what developers do with Redux.
