I fixed the problem directly with Patrick in a PM, if anyone is facing the same issue, the problem is that with these new settings the URL check is stricter.
Any URL you fill in setting should be a correctly encoded URL, the simplest solution is to use encodeURI in the console of a browser:
Take this URL for example: “/some-url?title=Foo bar:baz”
encodeURI("/some-url?title=Foo bar:baz")
Will give you:
/some-url?title=Foo%20bar:baz
