Proper way to create a box in the sidebar

Thanks Bob for the quick response.

Unfortunately it doesn’t work for me for some reason. I use TechNews theme and the newest Publii.

I copied the original language file here:

c:\Users\Feriman\Documents\Publii\sites\ferimancom\input\languages\technews.lang.json

I put (only) these lines into this file:

“listing”: {
“advertisement”: “My Replaced Text”

I synced my website, but nothing changed. I tested it in incognito mode as well.

Okay, in that case the sample on this below support page is wrong:

https://getpublii.com/docs/translate-publii-theme-to-another-language.html

It says in “For Advanced Users” part it’s enough to use this code:

"slider": {
"button": "Your button text here",
"slide": "Slide %s"

But I have to use like this:

{
"slider": {
"button": "Your button text here",
"slide": "Slide %s"
}
}

It works with the second one.

Anyway, thanks for your support!
