How to make a html anchor in my blog

how to add the widget in my left side bar.

Go to appearance > widgets, you can add widget to sidebar from there.

Doesnt appear what do i do wrong

I don't see any widgets have been added to the left sidebar.

Can you add any of WP core widgets to the left sidebar to test?

added a block and that works

Good, that means the widgets are working fine.

Can you try switch to twenty twenty series theme to see if that makes the plugin widget to work?

check i dont think it works

If so, then it's definitely an issue that the plugin needs to be dealing with.

The plugins have to be compatible with twenty twenty series themes.
