GM.xmlHttpRequest : Could Not Understand The URL

- 1 answer

I wanted to try ACQUA userscript for stackoverflow but I got an error :

Script error: 
Error: "GM.xmlHttpRequest : Could not understand the URL :
https://acqua.kmi.open.ac.uk/predict
TypeError: URL is not a constructor

I think it is "acqua.kmi.open.ac.uk", there is to many sub domain. How can I fix it ?

The userscript code :

// ==UserScript==

Answer

I think it is "acqua.kmi.open.ac.uk", there is to many sub domain

Not the issue at all.

URL is the name of an existing JS interface, https://developer.mozilla.org/en-US/docs/Web/API/URL

Name your variable something different.
