No funciona porque la direccion a la que llama ya no está disponible. Ahora está en "https://hackergpt.app/". Tendrás que modificar el plasmoide.

Благодарю за информацию, очень нравится этот виджет, а теперь и на шестой плазме можно использовать!

As it says, its for Plasma5 only. Since i use Plasma6 i can not use it. Would be nice the maintainer could bring it to Plasma6 as this is the current version for more than a year to this date.

You are rating a widget that is not for Plasma 6, this is wrong.

OK, I just wanted to use it under Plasma6 (plus Falkon Browser). To me its like using a todays browser/app/operating system but the extension is for Windows Vista only.
